市政工程邻近既有地铁区间变形控制分析

Deformation Control Analysis of the Section of Municipal Engineering Close to Existing Subway

基于红军营城铁桥桥区积水治理工程邻近地铁13号线立水桥站-北苑站区间工程,对新建暗挖调蓄池隧道以及管线邻近地铁区间路基结构变形控制进行了分析。通过Midas/GTS对施工过程进行数值模拟,分析并评价邻近施工对路基结构的影响,并采取相应的轨道防护措施,保证施工对地铁运营的安全。

Based on the water treatment project of bridge area of Hongjunying Chengtie bridge near by the section of Lishuiqiao station to Beiyuan station of Metro Line 13, this paper analyzes the deformation control of subgrade structure of the adjacent subway and the newly built underground storage tank tunnel. Through Midas/GTS, the construction process is numerically simulated, and the influence of adjacent construction on the subgrade structure is analyzed and evaluated. Corresponding rail protection measures are taken to ensure the safety of the construction of the subway.
