大型基坑施工对临近运营地铁影响分析

Analysis of influence of large foundation pit construction on the adjacent operation subway

某市地铁运营指挥中心大型基坑临近运营地铁车站及区间,其施工会对临近的运营地铁车站及区间产生一定的影响,特别是超近距离的基坑施工,必须对其安全性进行分析。文章运用数值模拟分析对大型基坑施工对临近运营地铁安全性进行评估,并针对近接地铁施工存在的风险提出相应防护措施,以期为本地区类似工程提供解决方案。

When a large foundation pit of a metro operation command and traffic control center in a city is adjacent to the metro station and section, its construction has some impact on the adjacent metro station and section. Especially for the very close foundation pit construction, its safety must be analyzed. This paper uses numerical simulation analysis to evaluate the safety of large-scale foundation pit construction to the adjacent operation metro, and proposes corresponding protective measures for the risk of adjacent metro construction, providing solutions for similar projects in this area.
