病险水库主要工程地质问题与勘察研究

我国早期建设的水库，由于当时建设标准偏低，缺乏统一标准，现大部分已接近设计使用年限，而且工程老化，年久失修，存在运行安全隐患。针对上述情况，分析了我国病险水库形成的原因；论述了病险水库的主要类型，以及坝体渗漏、滑坡、坝基沉陷、抗震稳定等主要险情的地质因素；提出了病险水库勘察的工作原则、阶段划分等，总结了病险水库勘察工作应注意的事项，为水库大坝安全评价和除险加固设计提供了依据。

Research on main engineering geological problems of dangerous reservoirs and survey

Many reservoirs constructed in early age of new China are dangerous due to several causes such as low construction standard,lack of unified standard,engineering aging,and poor maintenance for many years.In view of above problems,the causes for formation of dangerous reservoirs are analyzed;the main types of the dangerous reservoirs,and the geological factors including seepage and landslides of dam,foundation subsidence,seismic instability etc.are presented.The working principles and stages of investigation ...
