摘　　要：本文在系统整理研究窄巷口水电站已有勘察、试验成果的基础上，通过岩溶地质分析，综合运用各种水文地质测试方法，包括水位观测、地下水温度、电导率测量和示踪试验等，研究库首左岸防渗线的地下水渗流场、温度场、电导率场等物理场，各场相互印证，并以物探和钻探等手段加以验证。在大量勘察、分析工作的基础上，掌握了左岸岩溶发育的基本规律，查明了主要渗漏管道的位置、规模和形态，为防渗堵漏处理提供了翔实的地质资料。On the basis of systematically studying the investigation and test results of Zhaixiangkou hydropower pro- ject, the paper studies the underground seepage field on the bank of the head reservoir, temperature field, conduc- tivity field through analyzing karst geological and adopting various hydrogeological testing methods, including water level observation, underground water temperature, conductivity and tracer testing, and all the fields are confirmed each other, which are tested by geophysical exploration and drilling methods. On the basis of a lot of investigation and analysis, the basic law of karst development on the bank and the place of main leakage path are fined out to provide the detail geological data for anti-seepage treatment.
