Optimization of dewatering schemes for a deep ScienceDirect
Jun 01, 2018The dewatering design should consider the different hydrogeological conditions of each area of the foundation pit. A 3D numerical simulation was adopted to evaluate the effect of the dewatering schemes. This stone aims to propose the optimal dewatering scheme according to the simulation results and provide reference to similar engineering projects.
