摘　　要：运用温度电导率等示踪方法对广东韶关电厂濛浬灰场4号坝段漏水路径进行调查,通过几个观测孔多方面数据(包括温度、电导率、地下水位、地下水流速等示踪数据)的相互验证,结果证实,补给路径在上游流场从ZK4孔到ZK8孔向外伸展,呈弧形补给漏水点;降水在库区垂直入渗,沿初期坝与第一级子坝搭接处向上流动,最终在71.00m高程处出露形成漏水点。Leakage path of No.4dam section in Mengli ash yard of Shaoguan power plant was investigated using the tracing method of temperature and electrical conductivity.Through the verification of temperature,electrical conductivity,groundwater level,and groundwater flow velocity in several observation boreholes,the results suggested that the recharge path extends from ZK4 borehole to ZK8 borehole in the upstream flow field and forms the arc supply leakage point,and precipitation infiltrates vertically into the dam,flows upward along the contacting zone between the initial dam and first sub-dam,and forms the leakage point at the elevation of 71.00 m.
