【摘要】 外环隧道浦西近岸段基槽浚挖最深达28.41m,近岸处上口宽度达214m,关键是选择合适的岸壁保护结构。通过离心模拟试验以及数学模型的分析计算,采用地下墙构筑的格构型重力挡土墙,基槽最深处的格构墙宽28.4m、墙深48m,以后逐次递减,取得了较好的技术、经济效益。更多还原

【Abstract】 The selection of bulkhead structure type is crucial when the Puxi trench,close to the bulkhead,is dredged into the depth of 28.41m and the width of upper part of the bulkhead is 214m.Through centrifugal modelling and analysis of mathematics model,the cellular retaining wall made of diaphragm wall is selected as bulkhead.At the deepest point of trench,the retaining wall is 28.4m wide and 48m deep.And it achieves good technical and eco- nomic benefits.更多还原
