Abstract: Abstract:The land subsidence in China can be divided into two types: (1) the subsidence is mainly caused by excessive groundwater withdrawal; (2) the subsidence is caused by groundwater, oil, gas and warm groundwater withdrawal, which is superposed on the neotectonic movement. Not only do the different layers have difference deformation features, but also the same layers in the different location have different deformation features. Even the same layers in the same location have different features in different stage. The corresponding models based on the actual deformation features of the soil should be built in order to simulate the real subsidence condition. The couple of the models and the difference between the vertical and horizontal scales are the problems to be solved for the accurate simulation.
