水泥土墙内插门架工字钢在某基坑工程中的应用

The Application of the Cement-soil Wall Inserted Door Frame I-steel in an Excavations Engineering

通过某工程实例,介绍了水泥土墙内插门架工字钢支护的优势特点、设计方法和施工工艺;根据基坑开挖后监测数据的对比分析,证明运用该方法对深厚软土区基坑进行支护可以有效控制位移,并对邻近建筑物进行有效保护;为类似的基坑工程提供了可供参考的支护方法。

Through an engineering example,this paper gives an introduction to the retaining and protection of cementsoil wall inserted door frame I-steel＇s advantage characteristic,design method and construction technology;according to the analysis of monitoring data comparison after the excavation of foundation pit,that by using the method of deep soft soil foundation pit support can effectively control the displacement,and the effective protection of the nearby buildings;provides reference support method for the similar foundation pit engineering.
