五里冲水库枢纽区防渗帷幕渗漏问题研究中水文地球化学的应用

APPLICATION OF HYDROGEOCHEMICAL METHODS IN STUDIES ON THE LEAKAGE OF IMPERVIOUS SCREEN IN THE KEY CONTROL POSITION OF WULICHONG RESERVOIR

本文从水文地球化学综合分析方法出发，并利用灰色关联度分析方法和稳定同位素分析方法，分析最具有渗漏可能性的Ｚ４１孔、ＵＰ８孔两地的水温、水化学、同位素等信息与库水、帷幕后（帷幕下游）岩溶水的贴近程度，确定其地下水补给的主要来源。

Based on the hydrogeochemical multidisciplinary analysis, and the application of grey relational and stable isotopic analysis methods,the water temperature, the hydrochemistry, the isotopes of borehole Z 41 and UP 8 that may be greatly possible to be leakage,as well as the close degree of the karst water behind the screen have been analysed in order to determine the major recharge source of the groundwater,and judge if the screen may or not be leakage.
