Numerical Simulation Study on Three-Dimensional Seepage Field of Deep Excavation Dewatering in Thick Aquifer

Abstract:

This article describes the pumping test procedures and test results of the subway project 30m deep excavation dewatering in thick aquifer. A groundwater three-dimensional seepage numerical calculation model is established. We use the model to calculate and compare the calculated results and the actual results, obtain hydrogeological parameters by inversion. Further, we have a numerical simulation study on deep excavation dewatering with the hydrogeological parameters, the Simulation results and excavation pre-dewatering test results are consistent. Test results show that the model can reflect the deep excavation dewatering process with complex geological conditions.
