摘要
针对小浪底水库自1999年10月25日下闸蓄水以来,随着库水位的逐渐升高,两岸坝肩渗漏量有所加大,左岸山体渗漏问题突出的现状,为确保左岸山体稳定,经对左岸山体各部位的渗漏观测情况及库区水文地质条件进行分析,结合瞬变电磁法和同位素示踪法对渗漏通道的探测结果,提出了左岸山体防渗的综合处理措施:帷幕补强,封闭迎库入渗面,加强幕后排水。这些措施实施后,取得了260 m库水位下渗漏减幅达44%的较好效果。
Since the gate of Xiaolangdi Reservoir was closed for water impoundment, the leakage of two abutments has increased with the gradual rise of the reservoir water level, and the leakage of the left abutment was more serious. To ensure the stability of the left abutment, some comprehensive measures for seepage control were proposed based on an analysis of the investigated result of leakage at different parts of the left abutment and hydrological and geological condition of the reservoir region as well as the detected results of seepage passages by transient electromagnetic method and isotopic tracking method. Satisfactory result with the reduction of leakage of 44% was obtained at the reservoir water level of 260 m.
