摘要
研究和分析地下空间开挖对地表建筑物的影响,对进行城市地下空间规划和利用是很有必要的。本文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。
It is necessary for the plan and use of the city underground space to research and analyze the influence on the surface building arising from underground space excavating. This article based on certain subway development construction project, uses the ADINA finite element structure analysis procedure to analyze the characteristic and rule of ground surface deformation arising from the city subway excavating and the hale of rock＇s stress and displacement variation adjacent to the subway and building foundation is obtained. The ground deformation＇s influence on building is discussed, it offers a reference to the engineering design and the construction as well as the development and utilization of the city underground space.
