| 摘 要： | 本文采用数值模拟为手段分析了典型的隧道开挖方位对地面房屋结构的应力、位移和破坏的影响规律.研究表明当隧道从房屋正下方穿过时对房屋变形影响最大,最易发生破坏.其中,高应力区分布规律为:从正下方穿越时呈"八"加"一"字形;从左下穿过时呈"Δ"字形;从右下穿过时呈"U"字形.另外,房屋水平变形区与破坏区关系密切,隧道位置造成...

| Abstract: | With rapid development of urban tunnel construction,the stability problems of building structures induced by excavation of the tunnel become increasingly concerned.This paper presents a 3D numerical modeling study of the stress distribution,the deformation and the failure of one building structure when a tunnel was excavated at typical locations and directions.It shows that the worst case is that the tunnel is excavated below a building.It will result in the maximum deformation of the above building structu... |
