【摘要】 紧邻地铁车站的深基坑开挖容易导致地铁车站的倾斜和混凝土开裂,以长沙地铁某车站为工程背景,运用MIDAS/GTS有限元计算软件对地铁车站柱、结构板和地下连续墙进行数值模拟。重点分析地铁车站柱、结构板和地下连续墙的内力和变形,总结内力和位移的一般变化规律,通过与现场实测对比,验证了深基坑开挖的安全性。更多还原

【Abstract】 The deep foundation pin excavation adjacent to the subway station will easily lead to the tilt and concrete crack of the subway station. Taking the metro station in Changsha as an example, numerical simulations for column, structural plane and underground continuous wall of the subway station were performed with the aid of MIDAS/GTS. The internal force and deformation of these structures were emphatically discussed. The general change rules of the internal force and deformation were summarized. The safety of deep foundation pit excavation was finally demonstrated by comparing the results with the field measurement.更多还原
