摘　　要：基于龚嘴水电站绕坝渗流的监测数据,分析环境量变化对绕坝渗流产生的影响,结果表明:龚嘴水电站长期受库水位和降雨影响,未见明显绕坝渗流现象;上游水压和降雨是引起绕坝渗流的重要因素,同时也不能忽视地震(突变因素)对渗流可能引起的持久效应。Based on the monitoring data of seepage around the dam of Gongzui Hydropower Station,the impact of environmental factor variation on seepage around the dam is analyzed.The analysis shows that Gongzui Hydropower Station has been affected by the reservoir water level and rainfall for a long time,but no obvious seepage is found around the dam;upstream water pressure and rainfall are important factors that cause seepage around the dam,and the possible lasting effects of earthquakes(abrupt factors)on seepage cannot be ignored.

关 键 词：龚嘴水电站 绕坝渗流 环境量 地震
