摘要
洪屏抽水蓄能电站上水库水文地质复杂,不仅存在岩体和断层的水平渗透问题,也存在断层垂直渗透风险。通过对水文地质条件的分析,结合本工程渗漏控制要求,提出了主副防渗体系结合的方案,主防渗体系控制渗流量并确保建筑物运行安全,副防渗体系主要针对断层垂直渗漏,减小厂房排水压力。在防渗措施上,综合采用了库岸混凝土面板、帷幕灌浆、土工膜铺盖等多种方式,经防渗处理后,库盆防渗效果显著。
Because the complex hydrological and geological conditions of upper reservoir in Hongping Pumped-storage Power Station, there not only exist horizontal leakage channels in rock mass and faults, but also the vertical leakage channels in faults. Based on the analysis of hydrogeological conditions and combining with the requirements of project anti-seepage control, a combiniug scheme of main and auxiliary anti-seepage systems is put forward. The main anti-seepage system will control the seepage flow volume and ensure the operation safety of hydraulic structures. The auxiliary anti-seepage system mainly treats the vertical leakage of faults and reduces the drainage of underground powerhouse. The seepage control measures include reservoir bank concrete panel, curtain grouting, geomembrane blanket and others. After anti-seepage treatment, the anti-seepage effect of reservoir basin is remarkable.
