摘　　要：介绍了雨水管渠计算中的2种进水方式——传统进水和分散进水,通过比较2种进水方式的特点,提出了分散进水方式的雨水设计流量计算方法,并结合实例计算得出不同进水方式对设计流量计算方法的影响。结果表明,相同的设计条件下,使用分散进水方式计算的管渠设计流量整体大于传统的面积叠加法而小于流量叠加法。使用分散进水方式计算比传统方式更加接近实际,为雨水管渠的精准计算提供了新的思路。Two kinds of inflow modes in storm sewer calculation:traditional inflow mode and dispersed inflow mode were introduced.Through a comparison of features of the two inflow modes,a design flow calculation method of dispersed inflow mode was proposed.Combined with a practical case,the effects of different inflow modes on storm sewer design flow calculation method were discovered.The results showed that,under the same design condition,a calculated design flow in dispersed inflow mode was overall larger than that in traditional area superposition method and smaller than that in traditional flow superposition method.Compared to traditional method,dispersed inflow mode is closer to reality,which provides a new idea for precise calculation of storm sewer.
