摘要

为了分析海绵城市透水沥青路面结构力学响应,运用有限元软件ANSYS建立三维有限元路面模型,计算在车辆荷载作用下路面各结构层力学指标的变化规律。结果表明:基层厚度为表层排水型和基层储排水型透水沥青路面最主要影响因素;多孔混凝土层厚度为全透型透水沥青路面最主要影响因素。采用均匀设计方法,通过回归分析得到透水沥青路面各力学指标的计算公式。
        To analyze the mechanical response of permeable asphalt pavement structure in sponge city,threedimensional finite element pavement model was established with finite element software ANSYS to study the law how the mechanical index of each structural layer under vehicle load.The result shows that the thickness of the basement is the most important factor affecting the permeable asphalt pavement which is of surface drainage and base storage and drainage;and the thickness of the porous concrete layer affects the fully permeable pavement.Herein uniform design method was used,the formula of each mechanical index of permeable asphalt pavement was obtained through regression analysis.
