摘要

摘要: 通过构建人工模拟降雨与下垫面径流收集体系，解析城市不同非渗透下垫面径流系数。下垫面径流系数分析结果显示：城市道路平均径流系数为0.82，低于其他非渗透下垫面（0.87~0.89），这主要是由于沥青材质的城市道路具有更强的渗透性，其粗孔隙对水流具有较强的吸收能力。降雨历时和降雨强度是影响下垫面径流系数的关键因素。降雨历时对6种非渗透下垫面径流系数的影响均很显著，尤其是降雨初始20 min的时段，径流系数快速上升，最多超出起始4倍以上；降雨强度的增加势必引起产流时间缩短，加剧其对径流系数的影响，也使其与径流系数的相关性显著高于降雨历时。

Abstract: By constructing the artificial rainfall system and the collection system of underlying surface runoff, the runoff coefficients of different impervious underlying surface in the city was analyzed. The analysis results of runoff coefficients of underlying surface showed that the average runoff coefficient of urban road was 0.82, which was lower than that of other the non permeable underlying surface (0.87~0.89). This was mainly due to the stronger permeability of urban road made of asphalt material and the strong absorption capacity of its coarse pores to water flow. Rainfall duration and intensity were the key factors affecting runoff coefficient of the underlying surface. The influence of rainfall duration on runoff coefficient of six non permeable underlying surfaces was significant, especially in the initial 20 minutes of rainfall, and the runoff coefficient rise rapidly, which was more than 4 times of the initial value at most; the increase of rainfall intensity was bound to shorten the runoff production time, intensify its impact on runoff coefficient, and make its correlation with runoff coefficient significantly higher than rainfall duration.
