摘要
市政人行道结构设计计算方式较为单一。人行道铺装厚度与铺装方式与所承受荷载紧密相连,前期设计结构层荷载考虑不足会影响后期使用。随着国家大力推行海绵城市,人行道面层和基层的整体渗透系数与片区径流系数相关,仅考虑透水砖透水性不满足渗透要求,应对结构层整体进行考虑。该文对人行道结构层受力、渗透系数等作相关探讨,可为相关工程设计提供参考。
The calculation method of the structure design for municipal sidewalks is relatively simplex.The pavement thickness and method of the sidewalk are closely related to the load it bears,and insufficient consideration of the structural layer’s load in the early design stage would affect its application in latter stages.As sponge cities are being vigorously promoted,the overall permeability coefficient of the sidewalk surface and the base layer is related to the runoff coefficient of the area.Therefore,the overall structural layer should be considered,not just whether the water permeability of permeable bricks meets the penetration requirements.In this paper,the stress and permeability coefficient of the sidewalk’s structure layer were discussed,which can provide reference for related engineering design.
