Abstract: A case study on group pumping tests in Tianjin is carried out. A coupled model for dewatering and ground subsidence in a deep excavation project is established using Processing Modflow through analyzing the hydrogeology and engineering geology conditions. The parameters in the model are back calculated based on the measured data from the pumping test. The dewatering impaction of deep excavation on surroundings is predicted based on the amended parameters for different depth diaphragm wall. The advice for the excavation supporting design is proposed based on the prediction analysis and it achieved good results.
