11、來抑制端口的負載轉(zhuǎn)移，這是因為修建時采用了石頭和網(wǎng)膜。 在招標(biāo)圖紙上顯示了基礎(chǔ)頂部擴大樁，再運用早先經(jīng)驗， 佩爾指出這個設(shè)計方法可能被運用減少墊層的深度，并且把這種方法使用在城堡大橋上。 通過熔鑄一個擴大的部分1.1m在每樁上面，距離到樁下減少了1 m直徑，并且薄膜的間距在墊層的增加因而被減少了。 假設(shè)成拱形的作用在承臺依靠角度458從堆到墊層的上面，可能相應(yīng)地減少石頭的深度。通過合理的設(shè)計，墊層的整體深度從1500毫米減少了到900毫

12、米。 這樣減少了挖掘深度并保留了原始的底層。.</p><p>　　墊層路堤上升到最大高度6.3 m的車道高程。為了減少蔓延的路堤，招標(biāo)設(shè)計最初面臨混凝土預(yù)制板垂直側(cè)壁。這是后來修正的在投標(biāo)階段用紅磚砌筑的垂直墻壁，迫使改變設(shè)計中的鋼筋路堤。路基被分包兩個部分以坦薩為基礎(chǔ)和規(guī)范發(fā)展的佩爾弗里斯赫曼恩路段。其系統(tǒng)組成的單軸土工格柵在不同規(guī)定垂直間隔的壓實顆粒物質(zhì)。顆粒狀材料，符合高速公路規(guī)范做路堤材料的相關(guān)規(guī)定。該

14、一體來解決。并且利用墩臺的內(nèi)力來約束其相對移動。在招標(biāo)圖紙上還限制了必須要保持同樣的深度?，F(xiàn)在 從Y3到Y(jié)4進行簡化設(shè)計，這樣就會有更高的橋基、更大的樁和橋梁荷載，造成進口的材料損失。院長及安迪在這一共同目標(biāo)下進行了這項工作。凈厚40毫米的瀝青混凝土不僅滿足材料等級的要求，也適合使用在負荷傳遞的墊層上。此外，一直在現(xiàn)場進行永久材料的測試，而在興建河堤時，該材料很容易壓實，按要求使用1.5噸的振動壓路機碾壓，而且，就其性質(zhì)而言，非常適合埋

15、設(shè)在潮濕的條件。所有的測試結(jié)果顯示， 最低的壓實度在94 ％以上，壓實度遠遠超過承包商期望。</p><p><b>　　四、橋梁和橋墩</b></p><p>　　橋面包括預(yù)制預(yù)應(yīng)力混凝土梁和一塊跨度20m的現(xiàn)澆鋼筋混凝土平板。圖4和5顯示橋梁的長度和橫斷面。 在加強的橋臺建立支撐梁。在支撐梁區(qū)域凸顯了橋臺狹窄的特點，并且這些太狹窄的橋臺</p>&l

16、t;p><b>　　圖8 擋土墻</b></p><p>　　不能避免的退出工作結(jié)構(gòu)，并對混凝土砌塊側(cè)壁的河堤產(chǎn)生壓力。為了克服這個困難，把河堤的擋土墻在橋臺附近擴大，并使之成為完全擋土墻 (圖8)。 因為這變動太大以至于不能掩藏，在磚墻的上面放置的磚砌和預(yù)制混凝土做了加寬的區(qū)域，并在橋臺附近形成了壩肩。最后的布局給橋梁帶來了增值效應(yīng)并豐富了橋梁和其施工方法。</p>

17、<p>　　一旦澆注了混凝土，整個橋面將形成一個整體。 這方法消除了梁與支撐之間的轉(zhuǎn)動，因此，使橋面形成了一個統(tǒng)一的更加陡峭坡度。為了保持橋面產(chǎn)生壓力保持一樣，使橋面出現(xiàn)橫向的排水，這是招標(biāo)圖紙不允許的。 這就提出了一個南部路基高于預(yù)期150毫米。</p><p>　　設(shè)計要求在梁和橋面板之間容納一些復(fù)雜的服務(wù)設(shè)備。這些設(shè)備是一條250毫米直徑總水管(通過一條350毫米直徑輸送管)， HV電纜和一條四種

18、方式的BT輸送管。在招標(biāo)圖紙上看這些服務(wù)設(shè)備是在橋梁之間缺失的部分通過，而不是在它的下面通過。這些可利用的部分損失能夠使橋梁的自重更小、結(jié)構(gòu)減輕，而且橋梁的截面尺寸更大，這些臨時的設(shè)施在孔中通過。因此，要求作出詳細的安裝說明，這又是一個非常棘手的工作。</p><p>　　橋梁的布局方案是一個整體的固定結(jié)構(gòu)。并且，重新設(shè)計成了垂直路線，以適應(yīng)橋面的變化。這就導(dǎo)致了南部橋臺的升高，從而，橋面的坡度增加。因此，對上面

19、的橋梁產(chǎn)生了連鎖反應(yīng)。為提供合理的橋面跨越坡度，在橋南部的樁相應(yīng)的增長，在增長最多的地方增加深度超過300毫米。這要求在預(yù)應(yīng)力混凝土中增加更大預(yù)應(yīng)力。</p><p>　　在早期階段的合同中，院長及安迪把梁的施工作為一個關(guān)鍵階段， 尤其施工是在1月份進行。承包商要求在梁之間快速安裝永久模板，并且，要求在邊梁設(shè)計時插入臨時扶手欄桿。</p><p>　　澆注了橫跨橋梁護墻后，能夠掩蓋P6欄桿

20、末端。在安裝邊緣梁之前應(yīng)先安裝臨時扶手欄桿。在安裝所有的混凝土梁之前，承包商先安置永久模板。這種安裝方法安裝11根梁和所有的永久建筑僅僅需要5小時，大大的節(jié)省了施工周期。</p><p><b>　　五、護墻</b></p><p>　　標(biāo)準(zhǔn)型的P2護墻的目的是保護的邊緣河堤。因此，對該小組提出了相當(dāng)大的挑戰(zhàn)。必須在原先的位置澆注鋼筋混凝土，承包商對這種解決方案提出了

21、健康與安全問題，因為在地面上澆注6m的邊緣梁是十分危險的，必須要用到更多的腳手架和永久模板，并且，施工將延長幾個星期，工期將更加緊張。</p><p>　　為此，承包商建議使用預(yù)制混凝土欄桿來替代在原處澆注混凝土。然而，由于橋梁采用的是最小半徑，所以每個混凝土梁的長度受到限制，以避免出現(xiàn)外觀問題。并且計算表明混凝土欄桿會受到使用限制。</p><p>　　另外一種折衷的解決辦法包括一個預(yù)制

22、件和邊緣現(xiàn)澆的行人/自行車道建設(shè)，最終克服了這些問題。為了實現(xiàn)理想的效果，邊梁的預(yù)制需要的足夠的大小和形狀的磚塊，以確保邊緣的路堤穩(wěn)定。此外，雙方每個單位將需要略錐形，以適應(yīng)半徑的彎道，并且護墻后螺栓支持搖籃要預(yù)先安裝在正確的間距上。由于設(shè)計師和承包商通力合作，盤區(qū)類型的數(shù)量從30減少到17，排列在長度從最多3.65 m減少到最小限度1.98 m，并保留欄桿位置恒定間距沿堤防的主要長度（如圖9）。</p><p>

23、;　　預(yù)制的構(gòu)件通過現(xiàn)場澆注在一起，形成了一個整體。同時連欄桿和擴大的路堤也澆注在一起。把橋面板澆注在一起，使之形成梁。并且橋面板做了腳趾形設(shè)計，利用其摩擦力來抵抗欄桿的偶然荷載，用連續(xù)的橋面板和懸臂式結(jié)構(gòu)抵抗外部的對 橋面的扭轉(zhuǎn)和傾覆力。</p><p>　　P2支持部分被做成水平并且與橋梁完美的組合在一起。而末端被混凝土掩蓋保證了外觀的整潔。</p><p><b>　　六、

36、nt’s engineer, Arup, agreed general design principlesand the preliminary Approval in Principle (AIP) with NSDCprior to the issue of tender documents.</p><p>　　The contract was awarded to Dean & Dyball in

37、 July 2000 for atender value of £1·31 million and the contract period was set at34 weeks for a completion in April 2001. A simpli?edprogramme is shown in Fig. 2.</p><p>　　2. GROUNDWORKS</p>

38、<p>　　During the tender stage Pell Frischmann looked at a number ofre?nements to the tender design and following the award of thescheme undertook a full value engineering exercise in conjunction with the contractor,

39、 Dean & Dyball. The originaldesign called for steel H-piles under the bridge abutment areasadjacent to the railway line where limited vertical movement ofthe track was essential. Following a review of the groundcondi

40、tions and based on previous experience, the team successfully argued that c</p><p>　　The ground conditions at the site consist of made groundoverlying up to 19 m of soft alluvial clay. Below this either a2 m

41、 layer of ?rm/stiff clay on mudstone or sandstone bedrockexists. Two types of driven cast-in-situ piles were designed byKeller, 340 and 380 mm in diameter, to cope with the differentloading conditions caused by the bridg

42、e and the embankment.These were driven to refusal from the existing ground level. Thepoor ground contributed to rapid pile installation and rates of up to eig</p><p>　　A concrete pile cap was originally show

43、n above the H-piles todistribute the loads from thebridge abutments to the piles.By replacing the H-piles withthe driven cast-in-situ piles,but at slightly reduced spa-cing, it was possible to eliminate the pile caps and

44、 extendsaving on construction time as well as cost.</p><p>　　3. LOAD TRANSFERMATTRESS AND EMBANKMENTS</p><p>　　The piles were used to support a load transfer mattress,which was constructed froml

45、ayers of stone and geomembrane grids. Enlarged head piles had been shown on the tender drawing but, again drawing on previous experience, Pell Frischmann demonstrated that this design method could be utilised to reduce t

46、he depth of the</p><p>　　mattress and it was suggested that this approach be employed at Locking Castle. By casting an enlarged head of 1·1 m diameter at the top of each pile, the distance to the next p

47、ile was reduced and thus the span of the geomembranes in the mattress layers was decreased. Given that the arching effect in the mattress relies on an angle of 458 from the pile to the top of the mattress, the depth of s

48、tone could be reduced accordingly.</p><p>　　The overall depth of the mattress was reduced from 1500 mm to 900 mm by rationalising the design in this way. This also led to savings in reduced excavation to the

49、 original ground level (Fig.</p><p>　　3).Above the mattress the embankment rises to a maximum height of 6·3 m to carriageway level. To reduce the spread of the embankment, the tender design originally i

50、ndicated faced precast concrete panels to vertical sidewalls. This was amended later in the tender stage to vertical walls of class A red brickwork, forcing a change in the design of the reinforced embankment. The design

51、 of the embankment was subcontracted to Tensar, based on a speci?cation developed by Pell Frischmann. Their system c</p><p>　　The design of the embank-ment relies on the density of the compacted product bein

52、g structure. This does not reduce the design life of the structure which was set at the standard 120 years. Dif?cul- ties with this method of construction are well known and include accounting for differential settlement

53、, increased hogging moments at the ends of the beams and congestion of steel in the small areas between the beams. Suf?cient structural strength is inbuilt to counteract the stresses of one abutment </p><p>

54、　　4. BRIDGE AND ABUTMENTS</p><p>　　The bridge deck consisted of prestressed Y3 precast concrete beams and an in situ reinforced concrete slab spanning 20 mover the railway lines. Figs 5 and 6 show the long-

55、and crosssection of the bridge. The beams were supported on bankseats founded on the reinforced embankments. The narrow nature of the embankments was accentuated at the bankseat area sand it was soon obvious that these w

56、ere too narrow to avoidresting the structure on the concrete block sidewalls of theembankments. To overcome </p><p>　　Once placed, the PCC beams were cast into each bankseat by the addition of an integral en

57、dwall. This eliminated the need for bearings and movement joints, thus creating an integral and steeper gradients on the approach roads. Pressure to keep the deck construction as shallow as possible came also from the di

58、scovery that the original tender drawings had not allowed for a deck crossfall to shed water. This raised the southernembankment 150 mm higher than anticipated.</p><p>　　The design was further complicated by

59、 the requirement to accommodate services under the bridge deck, between the beams, and through the integral end wall. These services were a 250 mm diameter water main (through a 350 mm diameter duct), an HV electric cabl

60、e and a four-way BT duct. The loss of section was overcome by agreement to run the electric cable over the top of the deck, rather than below it, as it was not</p><p>　　physically possible to bring it throug

61、h the identi?ed location on the tender drawings. The loss of available wall section led to the requirement for smaller numbers of, but larger diameter, bars ?tted around the holes through the endwalls. This is turn made

62、 the detailing and ?tting of these bars one of the trickiest elements of the job.</p><p>　　Although generally ?xed by the layout of the overall scheme, the vertical road alignment was redesigned to accommoda

63、te the change in alignment of the bridge deck. This led to an increased gradient on the southern embankment but also had a knock-on effect on the loading of the bridge. To provide a reasonable rollover across the deck fr

64、om the steep gradients on either side, the depth of surfacing increased to over 300 mm at its deepest point. This greater loading increased the amount of prestressi</p><p>　　At an early stage in the contract

65、, Dean & Dyball had focused onthe placing of beams as a critical phase of the scheme,especially as the work was to be undertaken in January. Toaccelerate the placing of permanent formwork between the beams, the contr

66、actor requested that the edge beams bedesigned to include inserts to support the temporary handrails.</p><p>　　These were cast in at a depth such that they would be hidden in the ?nal scheme by tails on the

67、high containment precast P6parapet across the bridge. The temporary handrails were ?tted to the edge beams prior to placement (Fig. 8). This enabled the contractor to start placing permanent formwork before all the PCC b

68、eams had been laid. This approach reduced the time of track possession, with the eleven beams and permanent formwork all installed within ?ve hours.</p><p>　　5. APPROACH EMBANKMENT PARAPETS</p><p&

69、gt;　　Standard parapets of type P2 were designed to protect the edges of the approach embankments and the support for these presented the team with a considerable challenge. Originally shown as in situ reinforced concrete

70、, it soon became clear that this solution would provide the contractor with a signi?cant health and safety problem. Casting edge beams 6 m above the ground was potentially dangerous, required a lot of scaffolding mand pe

71、rmanent formwork, and would add weeks to the tight construction p</p><p>　　To overcome this, the contractor proposed using precast concrete parapet supports in lieu of in situ. However, due to the tight cent

72、reline radii on the bridge approaches (50 m radius), the length of each PCC section would need to be limited to avoid a ‘threepenny piece’ appearance. This created its ownproblems when design calculations showed that acc

73、idental loadings on the parapet would not be restrained by the use of small discrete PCC units.</p><p>　　A compromise solution consisting of a precast edge piece and an in situ section under the footway/cycl

74、eway construction was eventually developed to overcome the problems. To achieve the desired effect, the precast edge beam would need to be of suf?cient size and shape to rest on the brick/block edging of the embankment w

75、ithout being unstable. In addition, the sides of each unit would need to be slightly tapered to accommodate the radii of the bends, and the parapet support post bolt cradle would</p><p>　　The precast units w

76、ere tied together by means of an in situ element. This comprised a slab extending the entire length of the embankments from the bankseats to the end of the parapet units. The slab was cast continuously, without joints, s

77、o that it acted as a beam. The slab was designed with a toe, which, together with friction, counteracts the lateral forces from accidental loading of the parapet posts while the overturning forces of any impact are count

78、ered by the weight and cantilever effect </p><p>　　6. TEAM WORKIN</p><p>　　One of the most pleasing aspects of the scheme was the goodworking relationship that was maintained between all parties

79、. Although working under the General Conditions of Contract for Building and Civil Engineering GC/works/1,2the contractor was keen to espouse the ethics of partnering. Regular meetingsbetween the contractor, designer, cl
