| 摘 要： | 以佛山市越秀星汇云锦商业中心项目邻近已运营的广佛线桂城站及桂城站—南桂路站区间隧道为背景,采用Midas/GTS有限元软件,对该商业中心项目的基坑工程建立三维数值分析模型进行分析。在方案设计阶段采用施加基坑侧向位移来模拟地层损失继而导致地铁结构变形的简单模型,在施工图设计阶段采用动态模拟基坑开挖及回筑导致地铁结构变形的仿真模型。通过仿真计算为基坑设计和地铁结构安全评估分析提供了参考。

| Abstract: | Yuexiu-Yunjin Commercial Center-located at one side of subway station and tunnels-is taken as the background,and the Midas/GTS software is used for a 3-dimensional analysis of the envelop safety and the assessment of the effect of excavation during the pit construction.Then a series of effective measures are proposed to instruct the pit construction,from which more experiences will be accumulated for similar projects on pit construction in urban rail transit. |
