深基坑施工对临近地铁区间隧道不可避免产生一定的扰动,而软土地区又增加了深基坑变形控制的难度。对此,需要通过深基坑围护的合理设计,保证该工程的施工质量。本文从工程中常用的深基坑变形控制方法入手,结合实例,对软土地区紧邻地铁的深基坑围护设计进行分析和研究。
Deep foundation pit construction will inevitably produce some disturbance to the tunnel near the subway, while the soft soil area increases the difficulty of deep foundation pit deformation control. In this regard, it is necessary to ensure the construction quality of the project through the rational design of the deep foundation pit enclosure. This article starts with the control method of deep foundation pit deformation commonly used in engineering, and analyzes and studies the design of deep foundation pit support in soft soil area adjacent to subway.
