摘要
以广州某实际工程为例,采用FLAC3D有限差分程序,建立了基坑与周边地铁结构及支护体系的三维数值模型,对基坑施工过程进行模拟,研究了基坑施工造成邻近地铁出入口结构的位移增量及其变化规律,并基于此对地铁结构的安全性进行了评估,可为类似工程的分析提供参考。
Taking practice engineering in Guangzhou city for example,using the FLAC3D finite difference software,established 3D numerical model of foundation pit,underground surrounding subway structures and supporting system,to simulate foundation pit construction process,researched displacement increment and its variation regular of nearby subway exit and entrance structure caused by foundation pit construction,it is based on this to evaluate safety of the subway structure,and provided a reference for analysis of similar projects.
