摘要:随着我国市政交通的发展,地铁、轻轨深基坑工程越来越多。深基坑的支护结构直接影响着基坑工程的安全。本文以某市轻轨换乘车站深基坑工程为背景,在秋季温差较大的条件下,追踪监测基坑的支护结构受力变形规律,得出了一些有意义的结论,对类似条件的基坑工程的施工应有一定的借鉴意义。

Abstract: Following the municipal traffic development in our country, more and more deep foundation pit projects for the subway and light rail have been conducted. The pit support is the key factor of the pit safety. In this article, under the condition of serious temperature difference, the regular pattern of the pit support for a light station has been traced, and some positive conclusion has been given, which will be the useful references in other resembling foundation pit support structure of the subway and light rail.
Keywords: deep foundation pit, temperature difference influence, monitoring, discipline analysis
