不同基坑施工引起的围护结构变形及建筑物沉降对比分析

在城市环境中，如何控制地层移动以保证基坑周围临近建筑物的安全，是设计以及施工中必须考虑的问题。在监控量测基础上，详细对比分析了二元结构地层基坑开挖引起不同围护结构的变形情况及对周边环境的影响，对以后明挖基坑设计根据地质情况及周边环境的复杂性来选取围护结构参数及支护形式具有一定指导意义。

Comparative Analysis on Retaining Structure Deformation and Surrounding Building Settlement Caused by Different Foundation Pit Construction

The main issue that should be considered both in the design and construction of foundation pits in the urban environment is the controlling of the ground movement and the controlling of surrounding building settlement.The author makes a comparative analysis on the different deformation situations of the retaining structures and on the influence on the surrounding environment caused by excavation in dual-structure strata.This paper provides reference for the selection of the retaining structure parameters an...
