Abstract
In large-scale hydropower projects, the anti-seepage curtain is an important measure to reduce the leakage of reservoirs and ensure the stability of foundation rocks. In this study, an efficient procedure for the optimization design of an anti-seepage curtain was proposed given the drawback of the time-consuming and low efficiency in optimizing multiple parameters of the anti-seepage curtain. This procedure can dramatically shorten the time for numerical simulation, reduce the workload of planning multiple parameter sets, and effectively avert the probable distortion of optimized results to some extent. This is achieved by identifying and optimizing the parameter that has the greatest impact on the performance of the anti-seepage curtain on the premise of adequate geological investigation and proper qualification of the performance of the anti-seepage curtain. This procedure was applied to the optimization design of the anti-seepage curtain in the upper reservoir of a pumped storage power station. Four different depths were suggested for the anti-seepage curtain according to the optimization results. This procedure can serve as a reference for the optimization design of an anti-seepage curtain with high effectiveness and confidence.
