摘要
针对江西省水库管理存在的局限,探讨了区域水库群风险管理技术。详细介绍了大坝脆弱度的计算方法,提出了大坝风险指数指标体系的构建原则,并构建了大坝风险指数指标体系。结合大余县4座土石坝,分别开展了水库群风险指数计算。根据各级风险指数大小分布可知,工程缺陷仍是目前主要存在的风险,而管理缺陷相对偏弱;基于4级指标风险指数排序,提出了针对性的风险防控措施及建议,为提高水库风险管理水平提供技术方法。
In view of the existing problems of reservoir management model in Jiangxi Province, the calculation method of dam vulnerability is introduced in detail, the construction principle of dam risk index system is put forward, and the index system of dam risk index is constructed. Based on four earth-rock dams in Dayu County, the risk index of reservoir group is calculated. According to the distribution of risk indices at all levels, engineering defects are still the main risks at present, while management defects are relatively weak. Based on the ranking of risk indices at four levels, targeted risk prevention and control measures and suggestions are put forward. This paper provides technical methods for improving reservoir risk management level.
