大宁调蓄水库防渗工程应用效果监测及评价

Monitoring and evaluation on the effect of anti-seepage project in the Daning Reservoir

基于大宁调蓄水库库区监测数据,分析库外地下水位与库水位之间的相关性,总结地下水位变化规律,同时采用水量平衡法对库区渗漏量进行定量计算,进而对防渗工程的应用效果进行评价。结果表明,防渗措施起到了阻隔库水外渗的作用,与无防渗工程时相比,库区渗漏量显著减少。

Based on the monitoring data of the Daning Reservoir,this paper analyzed the correlation between the groundwater level outside the reservoir and the reservoir water level and summarized the law of the groundwater level variation.The water balance method was used to quantitatively calculate the amount of the seepage,and the application effect of the anti-seepage project was evaluated.The results showed that the anti-seepage works played a role in preventing the seepage of the reservoir.Compared with the case without anti-seepage works,the amount of seepage in the reservoir was significantly reduced.
