摘　　要：本文以云南省青少年科技中心还建项目位于昆明地铁5号线圆通山站车站上方施工为背景,在复杂条件下采用Midas GTS数值模拟软件建立三维动态模型对地铁车站上盖结构施工过程进行模拟,对地铁车站结构及轨道结构的影响进行了研究。研究结果表明上盖结构施工对地铁车站结构及轨道结构的影响可控,各项变形指标、边坡稳定性和内力变化均满足控制要求。This article takes the construction of the Yunnan Youth Science and Technology Center project located above the Yuantongshan Station on Kunming Metro Line 5 as the background.Under these complex conditions,a three-dimensional dynamic model was established using Midas GTS numerical simulation software to simulate the construction process of the subway station cover structure,and the impact on the subway station structure and track structure was studied.The research results indicate that the construction of the overlying structure has a controllable impact on the subway station structure and track structure,and all deformation indicators,slope stability,and internal force changes meet the control requirements.
