| 摘 要： | 在国家著名风景区下面修建多层大跨交通车站结构,具有复杂的施工程序和较大的施工难度。随着如何验证在施工过程中,景区文物有没有受到较大影响,成为工程建设前必须要解决的现实问题。针对新建京张城际铁路八达岭地下站这一实际工程,利用ABAQUS软件,分别建立了在八达岭山体中开挖斜井、竖井群洞和车站主体结构施工的三维有限元模型,模拟了斜井开挖、车站施工过程中对围岩及地表环境的影响。数值分析表明,在推荐的施工方案下,围岩位移和围岩应力均没有超过允许值,地表沉降对景区影响甚微,为该工程的实施提供了依据和指导作用。

| Abstract: | There are complicated construction process and great difficulties in building multi-storey and large-span station structures under famous national scenic spots.How to verify the construction's influence on the cultural relics is a practical problem to be solved before engineering.Based on the engineering practice of Badaling underground station in new Jing-Zhang Inter-city Railway,the paper used the software ABAQUS to establish respectively the three-dimensional finite element models of the excavated inclin... |
