摘要
自蓄水以来,小排吾水库渗漏问题就一直存在,虽经建库初期的坝内铺盖和多次除险加固,近坝库区及库底岩溶渗漏问题依然存在,且日趋严重。为解决这一问题,采用温度法、流场法、自然电场法三种示踪法对该水库岩溶渗漏进行了探测,并依据探测结果对水库进行防渗处理,效果显著。可见,综合示踪法可更准确、有效地探测出岩溶水库的渗流通道。
The leakage problem of Xiaopaiwu reservoir has existed since impoundment. After surface sealing and several times reinforcing in the construction period, the leakage still exists and becomes seriously. In order to settle the problem, three kinds of natural methods including temperature, flow field and natural electric field are employed to detect the leakage of reservoir. The remedial measure is taken based on the detection results and proved effective. It is shown that the natural comprehensive method could detect seepage of karst reservoir accurately and effectively.
