水库防洪调度线直接关系到水库安全的破坏率或一定破坏率条件下的水库兴利效益.因此,探讨其合理的计算方法,具有重要的实际意义. 习用的常规方法是,在假定每个分期的设计洪水过程线的设计频率相同,并等于大坝被破坏的概率的条件下,根据一定的设计标准,作出各分期的设计洪水过程线,然后再对这些过程线从已知的设计最高水位进行反向调洪计算,从而绘出相应的蓄洪过程线及其下包线,即所求的防洪调度线.这种常规方法的主要问题是,假定大坝在每个分 Reservoir flood control scheduling line is directly related to the safety of reservoir damage rate or a certain rate of damage under the conditions of reservoir prospering benefit.Therefore, to explore its reasonable calculation method, of great practical significance.It is customary to use the method, assuming that each staging Design flood process line design frequency is the same, and equal to the probability of damage to the dam conditions, according to a certain design criteria, the design flood process of each staging line, and then the process of these lines from the known design maximum water level The reverse flood regulation calculation, and draw the corresponding flood storage process line and its sub-envelope, that is, the flood control scheduling line.The main problem of this conventional method is that the dam in each sub-section
