摘要
淤泥质土物理力学性能较差,在基坑开挖工程中存在较大风险。文章以张家港市某基坑支护工程为研究对象,采用水泥土重力式挡墙的支护形式,并对坑内被动区加固处理,将支护结构的位移变形控制在合理安全的范围内;文中还对基坑局部发生的滑塌进行了分析,希望类似工程能引以为鉴。
The physical-mechanical properties of silty soil is so poor that there is a big risk in the excavation project. This study is based on a foundation pit project in Zhangjiagang City, which adopt cement-soil gravity retaining wall with passive zone reinforcedment, and the deformation displacement of supporting structure is at a reasonable safe range; Also, sliding foundation occurred locally were analyzed, it could provide references and suggestions for similar foundation pit projects.
