摘要
依据《海绵城市建设技术指南》,推求了山东省各地市5%步长年径流总量控制率对应的设计降雨量。在此基础上,采用线性插值法和指数模型拟合法对1%步长年径流总量控制率对应的设计降雨量进行快速计算。误差分析表明,两种方法在合适区间内都可以对设计降雨量进行快速、准确地计算。
According to the method in Technical guide of sponge city construction,the design rainfall of the capture ratio of total annual runoff volume at 5%step size was calculated in Shandong province.On this basis,linear interpolation and exponential model fitting were used in the rapid estimation of the design rainfall of the capture ratio of total annual runoff volume at 1%step size.The error analysis indicates that two methods could estimate the design rainfall rapidly and accurately in the appropriate interval.
