摘　　要：在城市飞速发展的同时,交通拥堵日益成为制约其发展的一大障碍,为此地铁以其快速畅通的优势在不少城市中兴建起来。结合昆明地铁实际工程,通过有限元软件Midas GTS对地铁区间隧道进行地震响应分析,研究其衬砌厚度对于地震响应的影响,对实际工程提供参考。As the city is developing rapidly, the problem of traffic congestion that limit the development of the city is becoming a big obstacle. The subway with its rapid unimpeded advantage is building up in many cities.Combining with the practical subway project in Kunming and using finite element software MIDAS/GTS, this pa- per analyzes the seismic response, studies the influence of the lining thickness change on the earthquake re- sponse. It hopes to provide reference for the actual projects.
