摘　　要：文章以T型换乘已运营轨道交通结构为研究对象,通过三维数值模拟,针对新建车站及暗挖段区间施工对已运营轨道交通结构的影响进行计算分析,验证施工对已运营轨道交通结构的变形、受力影响能否满足相关规范及运营要求,为该地区换乘轨道交通续建轨道结构的设计与施工提供一些依据和参考。In this paper,the T-shaped interchange in operational rail transit structures was deeply researched by three-dimensional numerical simulation.The impact of constructing new stations and tunneling sections on the operational rail transit structure was calculated and analyzed.This study verified whether the constructioninduced deformations and stress effects meet the relevant specifications and operational requirements.Some experience and reference are provided for the design and construction of the future rail transit structure in this area.
