Abstract: The data of multiple foundation pits over\|consolidation ratio in Changzhou area is counted. Taking the pumping test data of two sites, the splitting summation method and the subsidence calculation method considering stress history influence are compared and analyzed. The finite element software simulation results and subsidence monitoring results are compared. Research results show that compared with splitting summation method, the subsidence calculation method considering stress history influence provides closer results to monitoring ones of actual subsidence. This method can be used to quickly estimate the surrounding land subsidence value caused by dewatering under the condition of large drawdown and in areas with hydrogeological features similar to Changzhou.
