新建地下通道对地铁结构的影响分析

Analysis on Infl uence of Newly-built Underground Passage on Subway Structure

文章依托某邻近地铁的地下通道项目,利用Midas GTS就新建地下通道对地铁的影响进行三维分析,结果表明:施工引起的区间隧道变形及内力影响均在地铁结构安全控制标准范围内,因此该项目技术方案可行,分析方法和思路可为类似工程提供参考和指导。

Based on an underground passage project adjacent to the subway,this paper makes a 3D analysis of the influence of the newly-built underground passage on the subway by using Midas GTS.The results show that the deformation and internal force of the tunnel caused by the construction are within the scope of the safety control standard of the subway structure.Therefore,the technical scheme of the project is feasible.The analysis method and ideas in the paper can provide reference and guidance for similar engineering.
