索风营水电站水库岩溶渗漏分析及防渗处理建议

Analysis on karst seepage & suggestion of anti-seepage treatment of reservoir of Suofengying Hydropower Station

索风营水电站库区地质条件复杂 ,可溶岩广布 ,存在水库渗漏的不利条件。通过对岩溶含水系统及其地下水流动系统的研究 ,重点对 4个可能渗漏带进行了分析 ,论证了可疑渗漏带产生渗漏的可能性 ,得出了左岸库首存在岩溶管道渗漏的初步结论 。

Reservoir region of Suofengtying Hydropower Station has complicated geologic conditions, karst distributes widely, there are unfavorable conditions of seepage on it. Researching karst water bearing systems and flowing underground water, analyzing four key possible seepage areas, the writer demonstrated seepage possibility of questionable seepage areas. The preliminary conclusion is that there existed seepage through karst pipes on reservoir upstream of the right bank. Some suggestion schemes of treating the seepage are presented in this paper.
