Coupling model of land subsidence considering both effects of building load and groundwater exploitation

Abstract

Among the existing study of land subsidence, there is almost no consideration about the effects of building load and groundwater exploitation at the same time. Based on the consideration of these issues, this study designs the physical model test to simulate the subsidence effected by the building load and analysis the tendency of subsidence from the soil mechanics. Lastly, taking the typical geological structure of floodplain as an example, a coupling model is established considering both effects of building load and groundwater exploitation, its high accuracy of fitting and prediction shows that the coupling model can be used to simulate the land subsidence.
