【摘要】：城市排水系統(tǒng)的設(shè)計(jì)關(guān)系到國計(jì)民生，反映城市暴雨情況及規(guī)律的暴雨強(qiáng)度公式是研究城市排水系統(tǒng)的基礎(chǔ)，它的精度直接影響到城市排水管網(wǎng)設(shè)施工程安全性及合理性。 在城市化進(jìn)程中，城市的降雨情況及規(guī)律與暴雨強(qiáng)度均發(fā)生了較大的變化，應(yīng)用于大中城市的暴雨強(qiáng)度公式，已經(jīng)不再適合適用城市的發(fā)展。此外那些根本沒有適合其本身發(fā)展的暴雨強(qiáng)度公式的小城市，更不適合采用大中城市的暴雨強(qiáng)度公式。 本論文以山東省鄆城縣暴雨的自記降雨初始資料為基礎(chǔ)，，首先通過兩種選樣方法（最大值法和年多樣值法）對比、三種頻率分布模型(即皮爾遜-Ⅲ型分布、指數(shù)分布和耿貝爾分布)對所選樣本資料進(jìn)行擬合，通過優(yōu)化回歸分析法確定暴雨強(qiáng)度公式的模式及參數(shù)，最后確定適用于鄆城縣的暴雨強(qiáng)度公式。經(jīng)分析本論文選用年最大值法進(jìn)行對暴雨實(shí)測資料進(jìn)行選樣，采用指數(shù)分布適線法進(jìn)行對暴雨強(qiáng)度公式的推求。最后本文依據(jù)上述過程，推求得出符合鄆城縣暴雨情況及規(guī)律的暴雨強(qiáng)度公式。
[Abstract]:The design of urban drainage system is related to the national economy and people's livelihood. The formula of rainstorm intensity reflecting the situation and law of urban rainstorm is the basis of the study of urban drainage system. Its precision directly affects the safety and rationality of urban drainage network facilities.In the process of urbanization, the rainfall situation, law and intensity of rainstorm in cities have changed greatly. The formula of rainstorm intensity applied to large and medium cities is no longer suitable for the development of cities.In addition, those small cities which do not have the rainstorm intensity formula suitable for their own development are not suitable for the rainstorm intensity formula of large and medium cities.Based on the initial data of rainstorm in Yuncheng County, Shandong Province, this paper compares two sampling methods (maximum value method and annual diversity method), and three frequency distribution models (Pearson-鈪
