Abstract: Due to the design and construction technology of seepage control system, seepage of a plain reservoir in western China occurred after the impounding. Based on the original design and construction data as well as the site seepage location, high density resistivity method and ground penetrating radar detection were used to detect the groundwater level. According to the distribution of the underground water level in different sections, the seepage channel in dam foundation was  analyzed, which provided the technical support for the further design and construction of the seepage prevention.

Key words: reservoir, seepage, high density resistivity method, ground penetrating radar

摘要： 受防渗体系设计和施工工艺制约，西部地区某平原水库在蓄水运行后即发生了渗漏现象，影响水库蓄水和下游工程设施安全。在调研原有设计施工资料，以及现场渗漏位置的基础上，对该坝坝体和基础等部位采用了高密度电法和探地雷达检测地下水水位，并根据不同断面的地下水位分布情况，分析坝基中的渗漏通道，为进一步的防渗设计和施工提供了技术支撑。
