东吉湖库区防渗处理技术初探

以南京市东吉湖库区防渗处理工程为例,初步探讨了复合土工膜、粘土铺盖及垂直防渗墙在坝体防渗中的应用,从防渗效果、施工难度及经济合理性等方面,综合分析这三种处理方案的优缺点。研究表明,水库坝体防渗处理三种方案均是可行的,能够有效解决渗漏问题,改善水库的运行条件。通过综合分析比较,采用复合土工膜水平防渗与粘土斜墙垂直防渗相结合的设计方案,并论证分析该方案的科学合理及可行性。

Preliminary Discussion on Seepage Control of Dongjihu Reservoir

On the basic of the seepage control treatment project of Nanjing Dongjihu Reservoir,the article preliminarily discusses the application of composite geo-membrane,clay blanket and vertical anti-seepage wall in dam seepage prevention.The article comprehensively analyzes the advantages and disadvantages of three treatment schemes from the anti-seepage effect,construction difficulty and economic rationality.The study shows that three schemes of dam seepage control treatment are feasible,can efficiently solve the seepage problem and improve the operation condition of reservoir.By the comprehensive analysis and comparison,the design scheme combining the horizontal seepage prevention of composite geo-membrane and the vertical seepage prevention of clay slope wall is used.The article demonstrates and analyzes the scientific rationality and feasibility of this scheme.
