摘　　要：处在山体脚下的市政道路面临较大的汇水面积,针对其排水系统的设计难点,基于海绵城市建设的理念,通过对雨水汇流截流的计算,确定了以截洪沟、植草沟和道路雨水管为主体的三级排水系统,实现了雨水在区域内的自然积存、自然渗透和自然净化,达到了降低洪峰流量、提高市政道路抗洪排涝能力的效果。本方案在类似市政道路的工程设计中具有推广价值。Directing at difficulties of drainage system design for submontane municipal roads which are faced with larger catchment area,a three-stage drainage system with drainage channel,landscape ditch and municipal storm sewer as the main parts is designed by calculating the confluence and closure of rainwater,based on the design philosophy of sponge city. Through the drainage system, natural storing, infiltration and purification of rainwater within the area can be achieved, leading to decline of peak flow as well as improvement of flood control and drainage for municipal roads. In summary, the design disposal is worth popularization for the engineering design of similar municipal roads.
