基坑围护设计对邻近地铁结构影响分析

Analysis on Influence of Enclosure Design of Foundation Pit on Adjacent Metro Structure

基坑开挖会对邻近地铁结构造成附加的变形和受力,如果控制不当,甚至会引起区间与车站错位,从而影响地铁正常运营,因此对复杂条件下的基坑围护结构的设计计算也越来越为业内人士所重视。通过某一紧邻重要地铁结构的基坑围护设计,研究分析基坑开挖对周边管线的影响,为今后类似工程提供参照。

The excavation of foundation pit will cause the additional deformation and stress on the adjacent metro structures. The poor control will cause the dislocation between the interval and station so as to influence the normal operation of metro. Therefore, more and more people in the industry pay attention to the design and calculation of the enclosure structure of foundation pit in the complex conditions. Combined with the enclosure design of a foundation pit closely adjacent to the important metro structure, the article studies and analyzes the influence of foundation pit excavation on the peripheral pipelines, which can be referred for the similar projects.
