The model test research on land subsidence of Xian
The main compression layer of Xian is overconsolidation. Based on the property, the physical model is designed as a steel cylinder which is 2.5m diameter, 3m height. The soil layers are interbedded silty clay and medium-fine sand which are got in the building site of subway and house of Xian. We simulate the water lowering and the water recovering by changing the head in the medium-free sand layer. The data shows that the compression deformation have the consistency with the variation of stresses in the medium-fine sand ,but the compression deformation of the silty clay layer lagged to the variation of stresses. After the water pressure is lowering and steadying, the duration of expansion deformation is long, and based on the premise of no reducing the water pumping, reducing the settlement is possible by changing the type of pumping.
