软土地区深基坑施工与设计分析

Construction and Design Analysis of Deep Foundation Pits in Soft Soil Areas

文中以佛山地铁某号线车站为例,通过汇总和分析软土地质条件下类同围护结构形式的地铁车站的基坑实测数据,探讨该地质条件下设计方案对深基坑变形控制的影响,以及分析了确保基坑安全和有效控制深基坑变形的施工措施,为今后该软土地区类似工程提供参考。

Taking a station of a line of Foshan Metro as an example, by summarizing and analyzing the actual measurement data of the foundation pit of the subway station in the form of the same enclosure structure under soft soil conditions, the influence of the design scheme on the deformation control of the deep foundation pit under the geological conditions is discussed, and the construction measures to ensure the safety and effective control of the deformation of the deep foundation pit, so as to provide reference for similar projects in this soft soil area in the future.
