21、路段或有防洪要求時(shí)，采用M7.5漿砌片石護(hù)坡防護(hù)，防護(hù)高度超過(guò)設(shè)計(jì)水位0.5米以上。護(hù)肩、護(hù)腳墻：填土較薄或放坡時(shí)坡腳伸出比較遠(yuǎn)的路段，需要采用C20砼路肩墻、護(hù)腳墻支擋，擋土墻或路堤擋土墻，已確保路基穩(wěn)定，節(jié)約用地。擋土墻：受到建筑物或地形、地物的控制需要收縮占地地段，或錯(cuò)幅橋臺(tái)的中央分隔帶路段，填土相對(duì)較高的U形橋臺(tái)尾路段。設(shè)置現(xiàn)澆C20片石砼擋土墻，擋土墻采用重力式或衡重式路肩或路堤擋土墻。路肩擋土墻接近墻頂部預(yù)留C25砼護(hù)欄基座
