基坑工程过量位移问题的简析实例

A Brief Analysis of Excessive Displacement in Shanxi Huaji Foundation Engineering

汾河流域低阶地区广泛赋存有的高灵敏性饱和黄土类土会对建筑基坑带来困难,以华吉基坑工程为实例,在针对华吉基坑土质参数指标提出的支护和地下水控制方案的基础上,对基坑开挖及坑壁变形进行了描述,从岩土条件、饱和黄土特性等角度分析了产生的过量位移的原因,提出了支护结构安全性复核验算及补充加强措施并总结了经验教训。

The widely occurred high-sensitivity saturated loessial soil in low-rank region of Fenhe drainage basin will bring some difficulties to building foundation excavations. Take Huaji foundation engineering as an example, based on supporting scheme proposed by land parameter index of Huaji foundation and groundwater control, the foundation digging and pit walls deformation are described, from the angles of geotechnical conditions and saturated loessial soil features, reasons for foundation displacement are analyzed, safety checking computations of supporting structure are proposed, strengthened measurements are supplemented and some lessons are summed up.
