“水库调洪演算”是分析水库蓄洪削峰作用的一种计算方法,是水库设计(或除险加固设计)中一项很重要的水利计算,计算结果直接影响到所设计水库的溢洪道断面大小或大坝坝顶高程的高低。水库调洪演算的原理很简单,其基础就是一个水量平衡方程(见式1-1)。但是由于未知数q(溢洪道下泄量)与入库洪峰流量(Q)不直接相关,计算中需要引进h(溢洪道堰顶水头)、V(水库蓄水量)等中间变量,因而q的计算需要解一个非线性方程,比较麻烦。为了解决水库调洪演算中直接试算 “Reservoir flood regulation ” is a calculation method to analyze the role of reservoir in flood crest reduction. It is a very important water conservancy calculation in reservoir design (or reinforcement design), and the calculation result directly affects the spillway of the designed reservoir Section size or height of dam crest elevation. The principle of reservoir flood regulation is simple, and its foundation is a water balance equation (see Eq. 1-1). However, since the unknown q (spillway discharge) is not directly related to the peak discharge (Q), it is necessary to introduce intermediate variables such as h (spillway weir top) and V (reservoir storage) so the calculation of q needs to be solved A non-linear equation, more trouble. In order to solve the reservoir flood calculation calculation directly
