摘　　要：文章以天津地铁东南角站为例,针对十字换乘车站换乘节点两侧基坑非对称开挖工序,使用Midas GTS NX建立三维模型,模拟计算基坑开挖过程中既有运营车站的水平和竖向位移。基于计算结果,总结既有车站的变形规律,从而分析两侧基坑非对称开挖对中间既有站的影响,为设计方案和施工措施的制定提供数据支持,同时为类似工程提供参考。Taking Dongnanjiao Station on Tianjin Rail Transit as an example,aiming at the asymmetric excavation process of foundation pits on both sides of the transfer node in crosstransfer station,Midas GTS NX is used to establish a 3D model to simulate the horizontal and vertical displacement of the existing operating stations during the excavation of the foundation pits.Based on the calculation results,the deformation law of the existing stations is summarized,so as to analyze the influence of asymmetric excavation of foundation pits on both sides on the existing stations in the middle,which provides data support for the formulation of design schemes and construction measures,and provides reference for similar projects.
