摘　　要：我国许多城市正在考虑修建或已经在修建地铁以解决城市的交通拥挤问题。而地铁建设会引起地面沉陷,这有可能引发严重的安全及社会问题。因此,地铁施工引起的地表沉陷对地表的影响程度及其控制方法,是地铁建设者十分关注的问题,为此介绍了这一问题的有关工程实践与经验。Subways are in construction or to be constructed in many Chinese cities to mitigate traffic jam. However, the subway construction may lead to subsidence of ground surface, which may in turn lead to economic and safety damage. Consequently, the control methods of the subsidence are key problems in subway construction. In this paper, some engineering cases of subway construction are introduced, and experience is concluded on subsidence of ground surface and the control measures, which may serve as references to subway builders.
