Abstract：Cutoff wall is a common measure for hydraulic structures to reduce uplift pressure and hydraulic gradient,and its length and position have significant effects on anti-seepage control.To optimize the design of cutoff wall and control seepage risks,this paper adopts a genetic algorithm and finite element programming coupled model(GA-FEP),with construction cost minimization as the objective function and the safety factors of uplift pressure and hydraulic gradient meeting requirements as the main constraints.Quantitative analysis of the seepage field is conducted through finite element programming,and the genetic algorithm is used to determine the optimal depth and position of the cutoff wall.The results show that the model can obtain the optimal design scheme of the cutoff wall under specific head and hydraulic conductivity conditions.
