搜索法推求单重现期暴雨公式

To Inquire into Rainstorm Formula in Single Recurrence Interval by Searching Method

利用自计雨量计记录的降雨资料 ,推求城市雨水排水系统暴雨强度公式时 ,需要编制单一重现期暴雨强度公式。在图解法的基础上 ,作者给出了一种正确可靠、简单可行的电算方法。利用该方法编程求解单一重现期暴雨强度公式中的参数时 ,所得公式的平均绝对均方差可控制在 0 .0 5mm/min之内。

It needs to compile the rainstorm density formula in single recurrence interval, when inquiring into the rainstorm density formula of the urban rainwater drainage system by the rainfall data recoded by self-recording rain gauge. On the basis of graphic method the author gives a kind of correct, reliable, simple and feasible computer method. When programming and fining the solution of parameters in the rainstorm density in the single recurrence interval, the average and absolute mean square error of the formula to be obtained could be controlled in 0.05 mm/min .
