Fem Numerical Simulation of Certain Deep Foundation Pit Dewatering and Recharging

Taking an engineering project of deep foundation pit as an example,conditions of the recharging and drainage wells with different drawdown are simulated using finite element method.Then,the scheme of dewatering and recharging which not only meets the requirement of decreasing depth,but also effectively controls influence to environment is obtained on the basis of these numerically simulated results.Simultaneously,the reference law of optimal dewatering design in the similar engineering of deep foundation pit with the same geological condition is supplied,too.
