【Abstract】 The leveling data collected in Suzhou city since 1957 were processed and analyzed.According to the mechanics property of stratum and the data processing results,the vertical deformation reference datum is determined.By the method of spatio temporal analyses,deformation figure character value and nonlinear velocity calculating,this paper analyses the evolution process and deformation characters of ground subsidence in Suzhou city,which provides a base for integrated study of Suzhou ground subsidence.更多还原
