摘要 在复杂地质环境条件下的岩溶地区,抽水蓄能电站建设的可行性和安全性评价愈来愈受到重视。以陕西某岩溶地区的抽水蓄能电站为例,分析库区岩溶发育特征和水动力条件,利用数值模拟方法精细刻画库区复杂岩溶通道的空间形态,测算了潜在岩溶渗漏通道的渗漏量。结果显示,水库建成后,三个岩溶通道会发生严重渗漏,其中"一线天"渗漏量最大,为4 058.89m3/d,坝基和黑松梁渗漏量分别为3 564.69m3/d和3 085.23m3/d,在施加防渗帷幕措施后,各个岩溶通道的渗漏量明显减小。 It is thought highly on feasibility and safety evaluation in karst region particularly in complex geological environmental conditions.In this article,apumped storage power station in a karst area of Shaanxi province was taken as an example,karst development law and hydrodynamic condition of upper reservoir were analyzed,and a numerical simulation method was used to make fine description of space form of complex karst channel in reservoir,so as to predict potential karst leakage channel.The prediction results showed that three karst channels would be serious leakage after the completion of the reservoir,of which the maximum was ' First day',with the leakage of 4 058.89m^3/d,and the leakages of foundation and lodgepole pine beam were 3564.69m^3/d and 3 085.23m^3/d respectively.However,the leakages of karst channels decreased obviously after being applied the impervious curtain measures.
