摘要 十三陵抽水蓄能电站上水库进出水口区域局部渗漏量较大,可能存在集中渗漏通道。为确定渗漏主要部位,电站布置5条测线,采用小回线多源多分量瞬变电磁法对进出水口区域渗漏具体部位进行检测。综合利用不同发射源条件下多个分量的数据,对多种数据体进行联合反演,并结合进出水口区域运行期渗流监测分析资料,发现渗漏主要集中在低温季节,与地下水位无明显相关性,进出水口区域存在长度约10 m的渗漏异常区。本研究检测结果为进出水口集中渗漏通道查找及处理提供了技术支撑。 Local leakage in the inlet and outlet area of upper reservoir of Shisanling pumped storage power station is large,and there may be centralized leakage channels.In order to determine the main part of leakage,five survey lines are arranged in power station.The small loop multi-source and multicomponent transient electromagnetic method is used to detect the specific part of leakage.The multicomponent data from different emission sources are comprehensively used to carry out joint inversion.Combined with the seepage monitoring and analysis data during operation in the inlet and outlet area,it is obtained that the leakage is mainly occurred in low temperature seasons,which has no obvious correla⁃tion with groundwater level.And there is an anomalous leakage area with a length of 10 m in the inlet and outlet area.The detection results provide a technical support for the search and treatment of central⁃ized leakage channels at inlet and outlet.
