【摘要】 针对城市地铁车站基坑施工多在交通枢纽、建筑物密集环境之中,长时间的顺作敞挖严重影响市政交通环境,以武汉市地铁二号线某基坑的盖板半逆作施工为例,采用有限元数值模拟分析,重点探讨了不同盖板刚度对地连墙支护结构系统的力学响应。更多还原

【Abstract】 As a result of the open excavation of subway station,which would take long time of construction in subway engineering,environment function of civic traffic would be effected because pit of subway station was in adjacent of traffic pivot or in buildings.As a example of a subway station pit of Wuhan No.2 subway,numerical simulation analysis of FEM is used to cover plate semi-inversed construction method.Different cover plate stiffness influencing to mechanical response of supporting structure system about continuous concrete wall is analytical focal point in paper.更多还原
