摘　　要：针对上海地区的排水性沥青路,采用非饱和渗流理论,基于上海地区典型长历时63雨型24 h降雨强度,对道路断面进行降雨入渗数值模拟。计算分为稳态流、降雨瞬态流和排水瞬态流三个阶段,分析了降雨强度、道路宽度、道路横坡三个因素对道路排水性能的影响,对今后上海地区排水性沥青路面设计具有一定的借鉴意义。For the drainage asphalt road in the area of Shanghai,by using the unsaturated seepage theory,based on the 24 h rainfall intensity of typical long-duration rainfall(63 rain type)in the area of Shanghai,the numerical simulation of rainfall infiltration on road section is carried out.The calculation is divided into three stages of steady-state flow,transient rainfall flow and drainage transient flow.The effects of rainfall intensity,road width and road cross slope on the road drainage performance are analyzed,which has the certain reference significance for the design of drainage asphalt pavement in the area of Shanghai.
