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。

Construction and application of dam safety evaluation system for reservoir groups

In consideration of the characteristics of reservoir projects,a dam safety evaluation system for multi-reservoir region in Jiangxi Province was constructed,including the formulation of the technical specification for dam safety evaluation,the methods for risk evaluation of single reservoir dam project,the general plan for risk evaluation,danger removal and reinforcement of reservoir groups,the dam risk ranking,the defect and risk cause analysis,the evaluation of effect of schemes for risk removal and reinforcement,and the establishment of dynamic information management system for danger removal and reinforcement of reservoir groups.The system is of good effect of application in dam safety evaluation in Jiangxi Province.It can provide a scientific basis for decision makers and is of certain reference value to the similar projects.
