区域水库群大坝安全评价体系的构建

结合江西省水库群大坝安全评价工作,介绍了区域水库群大坝安全评价体系的构建过程,包括大坝安全评价技术标准的制定、单座水库大坝工程险度评价和风险评估、区域性水库群除险加固全面规划、水库群大坝安全风险排序、大坝病险原因分析及对策研究、除险加固方案的实施效果评价及区域性水库群除险加固动态管理信息系统的建立等内容。该体系在江西省水库群大坝安全评价中的应用效果良好,可为决策者提供科学依据。

The research and demonstration of some major geological problems of Three Gorges Project

The research process,main contents,methods and conclusions for some major engineering geological problems of the Three Gorges Project (TGP) are reviewed and introduced,including dam site selection,regional tectonic stability and seismic activity,stability of reservoir bank and reservoir-induced earthquake.Meanwhile,the above mentioned engineering geological problems are evaluated according to the preliminary test results since TGP operation and impoundment in 2003.
