隔河岩水利枢纽自１９９３年４月１０日下闸蓄水以来，渗流监测全面展开，至今已取得近４年的监测资料。实测渗漏量最大的部位为“左灌高程６０ｍ”平洞、１０～１８号坝段基础廊道和“右灌高程８２．５ｍ”平洞，它们也是各区域渗流监测的重点。根据１９９３年２月至１９９５年１２月的渗漏量和渗压监测资料，对重点监测部位的渗流特点作了初步分析后认为：隔河岩大坝基础不同的部位，因水文地质条件不同而呈现出不同的参流特点；渗控工程设计合理，施工质量良好，库水参漏很少，坝基扬压力远小于设计值。
The monitoring of percolation has been carried out in all aspects since Geheyan Water Control Project closed its gates and stored water on April 10, 1993. So far monitoring data have been obtained for nearly 4 years. The areas with the largest measured leakage are the “left irrigation level 60m” flat hole, the No. 10-18 basement corridor and the “right irrigation level 82.5m” flat hole, which are also the focus of percolation monitoring in all areas. According to the seepage and seepage pressure monitoring data from February 1993 to December 1995, a preliminary analysis of the seepage characteristics of the key monitoring sites is conducted. After that, the different parts of the Geheyan dam foundation are different due to the different hydrogeological conditions Showing different characteristics of the flow of participants; infiltration control project design is reasonable, good construction quality, reservoir water leakage is very small, the subgrade pressure is far less than the design value.
