非对称受力条件下的深基坑支护设计与实施经验

Experience in Design and Implementation of Deep Foundation Pit Support under Asymmetric Stress

摘要:

在片区开发过程中，地下空间往往连接为整体，而实际各相邻地块开发进度又有所不同，导致出现后期实施的深基坑围护结构所受水土压力不对称。现以软土地区某工程案例为依据，分析在非对称受力条件下深基坑的设计要点和后期实施效果。其成果可为其它相似工程作参考。

Abstract:

In the development process of the area, the underground space is often connected as a whole, and the actual development progress of each adjacent plot is different, which leads to the asymmetry of soil and water pressure on the retaining structure of deep foundation pit implemented in the later stage. Based on a project case in soft soil area, the design essentials and later implementation effect of deep foundation pit under the condition of asymmetric stress are analyzed, which can be a reference for the other similar projects.
