在体积径流系数法的基础上进行改进,提出控制径流系数法的概念与计算方法,并基于该方法对铁岭市降雨入渗控制指标体系进行了研究。首先对该市8个地区4种不同土地利用类型的96组土壤样品进行常水头试验,得到土壤饱和渗透系数,再计算各地区的控制径流系数及入渗控制径流量,最后根据计算结果总结了该市的降雨入渗指标体系及具体参数,从而为该市的城镇降雨入渗控制与管理提供科学依据。
Based on the volume flow coefficient method, the concept and calculation method of controlling runoff coefficient method are proposed. Based on this method, the index system of rainfall infiltration control in Tieling City is studied. First, 96 soil samples from 4 different land use types in 8 districts of the city were tested on a constant water head to get the saturated permeability coefficient of soil, then calculate the control runoff coefficient and infiltration control runoff in each region. Finally, according to the calculation results, The city’s rainfall infiltration index system and specific parameters, which for the city’s urban rainfall infiltration control and management to provide a scientific basis.
