摘　　要：水库渗漏是水库工程运行过程中的典型危害因素,查明水库的渗漏通道、来源及渗漏比例是保证工程安全、经济、高质量运行的关键。本文以山西蛤蟆神水库为例,基于物探解译、渗漏水的水化学特征和氢氧稳定同位素分布特征,使用系统聚类分析方法和混合比例模型,识别了渗漏点位的补给来源,计算了补给来源的转化比例。研究结果表明,水库渗漏点位的水源主要来自于水库右岸的绕坝、坝基渗漏和右岸山体的地下水的侧向补给。其中,绕坝、坝基渗漏约占渗漏点位水量来源的41.1%,地下水侧向补给约占58.9%。两个端元皆对渗漏点位贡献了相当的水源量,为水库除险加固和防渗帷幕布设方案提供了实际的参考意义。Reservoir leakage is a typical disease in the construction and operation of reservoir projects.Identifying leakage channels,leakage sources and proportion of the leakage is the key to ensure safe,economic and high-quality operation of the projects.In this paper,taking Hamashen Reservoir in Shanxi Province as an example,based on the geophysical interpretation,water chemistry characteristics and hydrogen-oxygen stable isotope distribution characteristics of seepage water,the recharge sources of seepage points are identified and the conversion ratio of the recharge sources is calculated by using the systematic cluster analysis method and the hybrid ratio model.The study results show that the water sources of the seepage site of the reservoir mainly come from the lateral recharge of seepage around the dam and the dam base on the right bank of the reservoir,and the groundwater from the right bank of the mountain.Among them,the leakage around the dam and the dam base accounts for about 41.1%of the water source at the seepage site,and the lateral recharge of groundwater accounts for about 58.9%.The contribution of the two end sources to the water volume at the seepage point is basically equal and needs to be taken into consideration when the reservoir is de-risked and reinforced,and the seepage curtain is arranged.
