峡谷型水库坝体渗流原因及防渗方案比选摘要：我国水库存在众多不稳定因素，分析出坝体的渗流原因并进行针对性解决的重要性变的越来越突出。本文以泾河中山峡谷水库为研究对象，对该水库的基本地质和工程情况通过注水、压水渗透等一些试验表明该坝体的填筑不够均匀，坝体质量比较差，坝基和坝体的防渗性能不好并且针对性的列出了四种坝体加固的常用方案，结合该水库坝体周围的地址具体条件对方案进行了对比，最终采用了固结灌浆的方案，以确保大坝的安全稳定运行，对于其他类似的工程具有非常重要的借鉴意义。关键词：坝体渗流；防渗性能；固结灌浆；稳定性评价；Cause analysis and seepage control scheme selection of gorge reservoir bodyAbstract: There are many unstable factors in China's reservoirs, and the importance of analyzing the causes of the seepage in the dam and making targeted solutions becomes more and more prominent. In this paper, Jinghe Zhongshan Canyon Gorge reservoir for the study, the basic geological and engineering conditions of the reservoir through water injection, infiltration of water pressure and other tests show that the dam body filling is not uniform, the dam body quality is poor, the dam foundation and dam Anti-seepage performance is not good. In addition, four kinds of common schemes for dam reinforcement are listed in detail, and the schemes are compared with the specific conditions around the reservoir dam. Finally, the consolidation grouting scheme is adopted to ensure the safe and stable operation of the dam, For other similar projects have a very important reference.Key words: Seepage flow in dam body; impermeability; consolidation grouting; stability evaluation;0 引言近年来，水库坝体稳定性不足、坝体渗漏、泄洪能力不达标等[1]这一系列问题如果不及时的进行有效处理，有可能酝酿成溃坝等重大事故[2]。本文以泾河中山峡谷水库为研究对象，对该水库的基本地质和工程情况通过注水、压水渗透等一些试验进行研究，表明该坝体的填筑不够均匀，坝...
