本文在分析现行雨水沟道计算理论的基础上,结合我国常用的三种暴雨公式(i=A/t~n,i=A/(t+b),i=A/(i+b)~n),以同频率控制的设计模式雨型为基础,就雨水沟道容量调洪理论中流量、集流时间的计算等问题,提出容最平衡调节法计算理论。 按本文推理导得的流量计算公式,可用于雨水沟道容量调洪理论的计算,并计入不同雨型对设计流量的影响;也可用于最大径流量的汁算,结合地区的暴雨特征与自然特征,经济合理地设计雨水沟道。
Based on the analysis of the calculation theory of the current rainwater channel and the combination of three rainstorm formulas commonly used in China (i = A / t ~ n, i = A / t + b, i = A / (i + b) Based on the same design pattern rain pattern with frequency control, this paper puts forward the calculation theory of balance adjustment method based on the calculation of flow and current collection time in flood channel theory. The flow calculation formula deduced in this paper can be used to calculate the flood control theory of rainwater channel capacity and take into account the influence of different rainfall patterns on the design flow rate. It can also be used for calculating the maximum flow rate. Combined with the regional rainstorm characteristics and Natural features, economical and rational design of the storm channel.
