本文通过人工模拟降雨技术,在46个测点上取得实测资料。采用曲线拟合法,得到了时间与地表径流系数的关系方程、渗透时间与渗透总量的关系方程、渗透时间与渗透速率的关系方程、渗透速率与渗透总量的关系方程,这些方程分别采用y=a(1-e~)~b、y=a+bx+cx~2、y=f_c+(f_o-f_c)e~、y=ae~(b/x)模型时,可以得到良好的拟合效果。并对46个测试区都作出了实测曲线的拟合方程,还对其渗透特性作了探讨。
In this paper, by artificial rainfall simulation technology, measured data obtained at 46 measuring points. Using curve fitting method, the relationship equation between time and surface runoff coefficient, relationship equation between infiltration time and total infiltration, relationship equation between infiltration time and infiltration rate, relation equation between infiltration rate and total infiltration were obtained. These equations are respectively expressed in terms of y A good fit can be obtained when a = a (1-e) ~ b, y = a + bx + cx ~ 2, y = f_c + (f_o-f_c) e ~, y = ae ~ (b / x) effect. The fitting equations of the measured curves were made for all 46 test zones, and the infiltration characteristics were also discussed.
