摘要
结合某地铁开发建设项目,采用ADINA有限元结构分析程序,分析了地铁开挖引起地表变形的特征和规律,得到了地铁及建筑物基础围岩的应力与位移变化规律,探讨了地表变形对建筑物的影响,对工程设计、施工及城市地下空间的开发利用提供了参考依据。
Combining some subway development construction item, the characteristic and rule of ground surface deformation arose from city subway excavating are analysed by use of the ADINA finite element structure analysis procedure,obtains the subway and the building foundation adjacent to rock＇s stress and the displacement variable rule. Discussing the ground deformation＇s influence to building, a reference is offered to the engineering design and the construction and the development use of the city underground space.
