Optimal Design of Foundation Pit Dewatering Based on Objective Functions and Numerical Analysis
Based on optimal designed objective function method, on the constraint condition of control point level and the objective function of the least total yield, optimal analysis of well-group precipitation design to the subway section has been done, and some targets have been gotten, such as the total yield, precipitation sphere of influence, reasonable arrangement of dewatering well and single-well water yield. At the same time assign for the single-well yield using COMSOL Multiphysics, and then simulate and evaluate the precipitation effect, predict the sphere of influence to surroundings caused by engineering dewatering and also the settlement regularity of the soil. It turns out that the combination of the above two methods can solve the optimal precipitation well to reach a better effect, reduce the cost and affect less environment.
