摘要
阐述了防洪限制水位物理意义、设置防洪限制水位的必要条件以及防洪限制水位设计应考虑的主要因素.从洪水信息获取方式,设计运用条件,调度运行规则等方面分析了防洪限制水位在水库设计与运行阶段的差异.总结了在水库长期运行中由于社会经济条件、运行管理体制变化对变动防洪限制水位的客观需求,并从高新技术应用、风险分析、水库特性等角度论述了防洪限制水位动态控制的可能性.提出实现防洪限制水位科学管理所亟待研究的课题.
A discussion is made on the physical meaning of the limit level for flood control, requirement for establishment of the limit level, and main factors which should be considered in design of the limit level. The difference between the limit levels for flood control in the reservoir design stage and its running stage is analyzed from the aspects of the approach to obtaining flood information, designed operation condition, operation management regulations of reservoirs, and so on. The objective requirements for the change of the limit level for flood control are summarized for the longterm operation of reservoirs under various socioeconomic conditions and operation management systems. The feasibility of dynamic control of the limit level for flood control is discussed from the viewpoints of hightechnique application, risk analysis, and reservoir characteristics. Finally, the subjects urgent to be studied on scientific management of the limit level for flood control are put forward.
