摘　　要：缘石坡道是指位于人行道口或人行横道两端,为避免人行道路缘石带来的通行障碍,方便行人进入人行道的一种坡道。缘石坡道坡面过陡、破损、缺失等不合理现象大量存在,给出行者造成不便,需要提出统一、合理的设置方法。文章在分析上海市现状缘石坡道的基础上,综合国内外设置情况,给出缘石坡道建议设计的尺寸与结构形式。在人流非密集区或人行道宽度不超过5.0 m处,缘石坡道正面坡道宽口取1.5 m。在人流密集区或人行道宽度大于5.0 m的大型商业区、广场区域,缘石坡道正面坡道宽口取3.0 m。结构形式推荐采用混凝土、石材或沥青,同时建议人行道盲道延伸至缘石坡道入口处,并设置提示盲道。Curb ramp refers to a ramp located at both ends of the pedestrian crossing or crosswalk,which is convenient for pedestrians to enter the sidewalk in order to avoid the traffic obstacles caused by the curb of the pedestrian road.There are a large number of unreasonable phenomena such as steep slope,damage and loss of curb ramp,which cause inconvenience to pedestrians.It is necessary to propose a unified and reasonable setting method.Based on the analysis of the current situation of curb ramps in Shanghai,and the setting situation at home and abroad,this paper gives the size and structural form of the proposed design of curb ramps.At places where the pedestrian flow is not dense or the sidewalk width is not more than 5.0 m,the width of the front ramp of the curb ramp is 1.5 m.In densely populated areas or large commercial areas and square areas with sidewalk width greater than 5.0 m,the width of the front ramp of the curb ramp is 3.0 m.It is recommended that concrete,stone or asphalt be used as the structural form.At the same time,it is recommended to extend the sidewalk blind path to the entrance of the curb ramp,and set up a prompt blind path.
