摘要
通过对城市降雨径流规律及碎石中水流运动的研究,建立了在快速干道特定条件下的降雨-径流计算模型,包括暴雨计算、路面产汇流、盲沟汇流和管道汇流四大部分。在暴雨计算中采用模式雨型法;路面产流用平均后损法,汇流采用扩散波法;盲沟汇流应用碎石中的水流运动方程,并用preissman格式差分求解;管道汇流用完全圣维南方程法。
Based on the research of civil hydrology and hydraulics, a hydraulic model of fast arterial highway's integrated drainage system was set up, which consists of 4 parts: calculation of rainstorm, calculation of flow generation and influx on road surface, the flow influx in infiltrative canal and the flow influx in pipelines.
