摘　　要：随着上海轨道交通网络的高速发展,在地铁车站基坑开挖时,往往会遇到旁边就是运营中车站的情况。作者以分析基坑开挖引起紧邻车站变形为目的,对实际的基坑开挖进行数值模拟。通过数值模拟分析,研究了张杨路地铁车站基坑开挖时新旧两车站间距、源头变形、土体弹性模量三个因素对在运营车站变形的影响,从而得到一些有用的结论。With the development of traffic net, many excavation projects are built adjacent to the subway station. In this paper the excavation construction is simulated to study the displacement of station near the foundation pit excavation. Through numerical simulation, the effect of distance between two stations, original deformation and young's modulus of soil on the regularity of station displacement is studied and some available conclusions are achieved.
