基于温度示踪原理的水库渗漏探测研究

Study on Reservoir Seepage Detection Based on Temperature Tracing Principle

土石坝工程的渗漏问题一直受到关注,为了有效治理土石坝渗漏,首先必须查明其渗漏的形式、位置、渗漏强度以及渗漏范围,因此长期以来,土石渗漏探测研究已经成为水利工程和岩土工程的一个重要研究课题。文章以某水电站工程为例,采用温度示踪法,对探测区域的地下水渗漏水来源、渗漏通道等问题进行了研究,确定了渗漏水的补给源,对坝体渗流分布状况进行了评估,相关研究方法可为类似工程提供参考。

Seepage of earth-rock fill dam draws attention all the time. To have the seepage treated, the seepage type, location, strength and scope shall be investigated clearly. Therefore, the study on the earth rock seepage detection becomes one important subject of the wa- ter resources and geoteehnical works. One hydropower station is taken as an example in the paper and the temperature tracing method is applied, the ground water seepage source and passage, etc of the detected area are studied. The seepage supply is determined and the dam seepage distribution is assessed. The study method may provide the similar projects with reference.
