摘　　要：随着地铁规模化建设和网格化发展,地铁隧道下穿既有建筑是不可避免的。目前,隧道下穿既有建筑时,盾构为首先工法,但其造价要远高于矿山法。以某地铁隧道下穿某实验室的实际工程为依托,利用MIDASGTS软件进行三维模拟分析,研究矿山法在隧道下穿既有建筑物工程中的可行性,提出隧道下穿既有建筑物的一些针对性技术措施,为类似工程提供参考。With the extensive construction of subway,it is inevitable to construct the subway tunnel beneath the existing buildings.At present,the primary method used in constructing a tunnel beneath the existing building should be shield method which costs much more than the mine tunneling method.Based on the example of a subway tunnel constructed beneath a laboratory,this paper tends to use MIDAS GTS software for three-dimensional simulation to study the feasibility of constructing a subway tunnel beneath the existing building by applying mine tunneling method.It also proposes specific technical measures in constructing the tunnel beneath the existing buildings and provides a reference for similar projects.
