摘要
水电站大坝坝基渗漏通道的确定及监测是进行坝基渗漏处理的关键。本文通过对观音岩水电站上下游河道、坝体渗水点及廊道内排水孔的水温和p H值进行检测,结合渗控监测资料分析,研究渗漏量与温度和p H值之间的关系,确定水电站坝基渗漏的主要来源和通道走向。此检测法无损伤、干扰小、成本低,可在类似坝基渗漏分析中应用。
Determination and monitoring of dam foundation leakage channels in hydropower station is the key to treatment of dam foundation leakage. Water temperature and pH value of upstream and downstream channel, seepage point of the dam body and drainage hole in the corridor of Guanyinyan Hydropower station are tested in the paper. Analysis on the seepage monitoring data is combined for studying the relationship among leakage amount, temperature and pH value. Main source and channel trend of dam foundation leakage in hydropower station are deternfined. The detection method has no damage, little interference and low cost, which can be applied to the analysis on sinfilar dam foundation leakage.
