明挖隧道基坑施工对邻近建筑物的影响分析

Analysis for Influences of Foundation Pit Construction of Open Excavated Tunnels on Adjacent Buildings

某新建安置房小区位于市域铁路隧道的影响区范围内,为评估铁路隧道基坑安全系数是否满足相关规范要求,文章根据隧道基坑结构设计方案,通过数值模拟分析基坑开挖对安置房的影响,结果表明隧道基坑采用地下连续墙方案,安置房结构变形在安全控制标准内,满足其正常安全使用。

A placement housing is located in the influence area of urban railway. Based on the structure design method of foundation ditch and security level,the effect of foundation pit excavation on the placement housing is analyzed by numerical simulation to evaluate whether the safety coefficient of rail tunnel foundation ditch meets the requirements of relevant specifications. Result shows that by using diaphragm wall method, the structure deformation meets the requirements of safety and normal service.
