基坑开挖对临近地铁结构安全影响分析

Analysis on the Influence of Excavating Foundation Excavation on the Safety of the Subway Structures Nearby

选择广州地铁5号线沿线某房地产开发公司的5017地块物业开发项目为实例,从工程水文地质条件入手,利用三维有限元技术,针对基坑施工和开挖的全过程进行数值模拟,得出各阶段隧道结构的变形情况,并对设计方案提出建议与意见。

This article selects the 5017 plot property development project of a real estate development company along the Guangzhou subway line No. 5 as an example,starting with the engineering hydrogeological conditions,the three-dimensional finite element technology is used to simulate the entire process of the foundation excanation construction and excavation,and the tunnel structure in each stage is obtained. Deformation,and make suggestions and opinions on the design proposal for similar projects.
