The ground deformation of a typical reclamation area in Chongming East Shoal, Shanghai was monitored by the SBAS method. Moreover, corresponding the monitoring results to the soil properties with field investigation and laboratory tests. The soil properties including physical and chemical properties, compressibility, micropore distribution and microstructure characteristics, are studied, and then the monitoring results are reasonably interpreted, providing a reference for future construction.

This paper analyses the design, construction and operation of the whole process of foundation pit dewatering and contains some research on the integrated design of foundation pit dewatering and a waterproof curtain, information control and groundwater artificial recharge. The measured data of groundwater level, pore water pressure and land subsidence show a good effect of land subsidence prevention and control.
