软土地区土的内摩准和粘聚力C很小,且地下水位较高,给深基坑的支护工作带来了困难。了解软土地区不同基坑支护形式的受力特点与变形情况是进行方案选择与基坑施工的前提。本文通过对软土地区地下连续墙结合内支撑、排桩结合内支撑、复合土钉墙、多支护组合等4个典型的基坑支护工程实例的监测成果进行分析,论述软土地区基坑支护的受力特点与变形规律,并得出相关结论。
The quasi-cohesion and cohesion C of the soil in the soft soil area is very small, and the groundwater level is high, which brings difficulties to the support of the deep foundation pit. Understanding the force characteristics and deformation of the different types of foundation pit support in soft soil area is the prerequisite for scheme selection and foundation pit construction. This paper analyzes the monitoring results of four typical foundation pit supporting projects such as underground continuous wall combined with internal support, row piles combined with internal support, composite soil nailing wall, and multi-supported support in soft soil, and discusses the basis of the soft soil region. The stress characteristics and deformation laws of the pit support and related conclusions are drawn.
