摘要
生活用雨水集流系统设计计算的任务 ,就是确定最优的集流场面积和贮水窖容积 ,即满足生活供水需求的集流场面积和贮水窖容积的最小值。以频率为 75 %和 95 %的特征水文年为基本计算年份 ,以降雨期的降水量、间雨期持续日数、最大间雨期日数和人均日需水指标为参数 ,根据逐日降水资料 ,计算出豫西山地各代表站的最优贮水窖容积和最优集流场面积。
The tasks of the design calculation of rainwater catchment system for life purposes are determining the optimum rate area of rainwater catching field and the first rate volume of water cellar, which are the minimum area of rainwater catching field and the minimum volume of water cellar which can meet the needs of supplying life with water. Taking the characteristic hydrologic year that its frequency is 75% and 95% as the basic calculating years, and taking the precipitations of rainfall periods, the days of non rainfall periods, the days of the maximum non rainfall period and the index of per capita water need as the parameters, according to the precipitation data day by day, the first rate volumes of water cellars and the first rate areas of rainwater catching fields in the mountain areas of west He'nan province are calculated.
