加筋土擋土墻畢業(yè)設(shè)計

1、[標簽:標題]篇一：畢業(yè)設(shè)計—加筋土擋土墻設(shè)計摘要加筋土擋墻是由拉筋、墻面板和填土構(gòu)成的一種新型復(fù)合支擋結(jié)構(gòu)物。相對于傳統(tǒng)的重力式擋土墻，加筋土擋墻為一種柔性結(jié)構(gòu)，具有較好的變形協(xié)調(diào)性和抗震性能，對地基的承載能力要求也不高，且具有很好的經(jīng)濟性和造型美觀性等一些其他結(jié)構(gòu)無法比擬的優(yōu)越性。因此，被廣泛應(yīng)用與公路、水利、城市建設(shè)和鐵路等工程中。加筋擋土墻雖有較好的抗震性能，但并非能夠抵抗任何等級的地震作用。對于規(guī)范要求的抗震設(shè)計加筋土擋墻工程

2、，在設(shè)計計算時須考慮地震力對其的影響。根據(jù)現(xiàn)行相關(guān)規(guī)范，地震烈度在6度以上的地區(qū)，加筋土擋墻應(yīng)進行抗震設(shè)計。采用擬靜力法來考慮地震作用，不計豎向地震力的影響，只需考慮水平地震力作用。本文對加筋擋土墻的構(gòu)造、特點及其發(fā)展應(yīng)用狀況作了概述。通過加筋擋土墻的構(gòu)造，分析了加筋擋土墻的加固機理和破壞模式。加筋土本身是一種復(fù)合結(jié)構(gòu)，在工作態(tài)下，各組成部分之間的相互影響使其具有一定的復(fù)雜性。關(guān)鍵詞：加筋土擋墻；地震力；穩(wěn)定性分析與計算Abstract
