For the design of foundation pit dewatering,it is necessary to conduct pumping tests in the early stage and obtain hydrogeological parameters through the tests.On this basis,the integrated design of foundation pit support and dewatering is carried out.This article uses Modflow to calculate hydrogeological parameters through unstable flow through pumping tests.Based on the analysis of hydrogeological conditions,a hydrogeological conceptual model and digital model are established to simulate and calculate the three schemes of the curtain for cutting off drains.The ground subsidence around the foundation pit is predicted,and the design scheme of the curtain for cutting off drains is recommended based on the actual engineering precipitation.
