Computation and prediction of the land subsidence in Taiyuan

To analyze the cause of land subsidence in Taiyuan,geologic model of Taiyuan City is generalized.A numerical model for computing land subsidence induced by extracting groundwater is developed.At the same time,the land subsidence of research region is forcasted.The results indicate that the land subsidence is mainly induced by the reduction of water level in deep water-bearing strata.
