Land subsidence is one of typical geological disasters at present. From 1990＇s, the land subsidence induced by engineering environmental effect has become a new cause in Shanghai city. The replicating effect of land subsidence induced by the dense high-rise building group and the effect of building high-rise buildings on the environment near the site are preliminarily researched in this paper, which can offer reference to control the land subsidence induced by the dense high- rise building group.
