下列術(shù)語和定義適用于本文件。

3.1

降雨量

某一時(shí)段從天空降落到地面的未蒸發(fā)、滲透、流失的雨在水平面上累積的深度。

注：以毫米（mm）為單位。

[來源：QX/T489-2019，2.2]

3.2

降雨歷時(shí)

降雨過程中的任意連續(xù)時(shí)段。

注：以分鐘（min）為單位。

[來源：GB50014-2021，2.1.9]

3.3

暴雨強(qiáng)度

單位時(shí)間內(nèi)單位面積上的降雨體積。

注：以升/（秒·公頃）（L/(s﹒hm2)）為單位。

DB5309/T83-2025

3.4

暴雨重現(xiàn)期

經(jīng)一定時(shí)間的雨量觀測(cè)資料統(tǒng)計(jì)分析，大于或等于某暴雨強(qiáng)度的降雨出現(xiàn)一次的平均間隔時(shí)間。

注：以年（a）為單位。

3.5

暴雨強(qiáng)度公式

反映短歷時(shí)暴雨過程中暴雨強(qiáng)度（q）-降雨歷時(shí)（t）-重現(xiàn)期（）三者間函數(shù)關(guān)系的數(shù)學(xué)表達(dá)式，

適用于城市小區(qū)域降雨規(guī)律的定量描述。其表達(dá)式為：

..............(1)

167A1(1+ClgP)

q=(t+b)

式中：

q---設(shè)計(jì)暴雨強(qiáng)度，單位為升/（秒·公頃）[L/(s﹒hm2)]；

P---設(shè)計(jì)暴雨重現(xiàn)期，單位為年（a）；

t---降雨歷時(shí)，單位為分鐘（min）；

A1---雨力參數(shù)，經(jīng)驗(yàn)參數(shù)；

C---雨力變動(dòng)參數(shù)，經(jīng)驗(yàn)參數(shù)；

b---降雨歷時(shí)修正參數(shù)，經(jīng)驗(yàn)參數(shù)；

n---暴雨衰減指數(shù)，經(jīng)驗(yàn)參數(shù)。
