为了分析相关参数对排水路面渗流特性的影响，应用渗流力学理论推导并建立了排水面层渗流运动模型。采用四阶的Runge-Kutta公式求得排水层最大潜水厚度的数值解，并对数值解进行回归分析，得到了最大潜水厚度与其他各参数之间的回归方程，依据该方程计算得到的降雨强度理论值能够较准确地反应实际使用情况。该方程表征了排水面层在一定的降雨强度下不出现地表径流的条件，可以指导排水路面排水层厚度的选择以及排水性沥青混合料目标空隙率的确定，为排水性路面功能特性和耐久性的协调提供了理论依据。

In order to analyze the effects of the related parameters on the geometrical characteristics of the porous asphalt pavement,a seepage movement model of the porous surface layer is established according to the mechanics of fluid flow.The maximum depth is solved in a numerical way by using the Ⅳ order Runge-Kutta method.The regression equations between the maximum depth and other parameters are obtained by using regression analysis on numerical results,and the theoretical values of the rainfall intensity calculated by this equation can reflect the actual situation accurately.These equations exhibit the condition of no surface runoff of the porous surface layer under certain rainfall intensity,which can guide the choice of the thickness of the porous asphalt layer and the aid void of the porous asphalt mixture.The conclusion provides a theoretical basis for the coordination of fea-tures and durability of the porous asphalt pavement.
