洪屏抽水蓄能电站上水库库盆三维复杂渗流场分析

3-D Seepage Field Analysis for Upper Reservoir Basin of Hongping Pumped-storage Power Station

水库渗漏问题以及库区的防渗处理一直是抽水蓄能电站库盆渗控研究的重点。对洪屏抽水蓄能电站复杂地质条件下的库盆进行整体三维有限元模拟,采用复合单元法对库区复杂地质条件进行概化,分析了库盆防渗帷幕渗控效果及断层的影响,并提出相应的改进意见。

The leakage and anti-seepage treatment of reservoir has been the study focus of reservoir basin seepage control in the construction of pumped-storage power station. A 3-D FEM simulation model is established herein to study the seepage field of upper reservoir basin in Hongping Pumped-storage Power Station, in which the composite element is used to model the complicated geological conditions. The effects of anti-seepage curtain wall and the affects of faults on seepage are analyzed by the model and some suggestions on seepage control are proposed based on the simulation results.
