峡谷型水库坝体渗流原因及防渗方案比选(论文4600字)
摘要:我国现阶段众多的水利工程经过多年的运营之后逐步的显露出了许许多多的不安全因素,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,以确保大坝可以在施工及以后安全运行,坝体的稳定加固工程明显有效,并且对于其他类似的工程具有非常重要的借鉴意义。

Cause analysis and seepage control scheme selection of gorge reservoir body
Abstract: After many years of operation, many water conservancy projects in our country gradually revealed many unsafe factors. It is becoming more and more important to analyze the causes of seepage of dam bodies and to make targeted solutions. 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 scheme is compared with the specific conditions around the reservoir dam. Finally, the consolidation grouting scheme is adopted to ensure that the dam can be constructed and later Safe operation, the dam reinforcement project is obvious and effective, and for other similar projects have a very important reference.
