摘要
在确定全透水人行道材料配合比及结构层厚度基础上,制作比尺模型并进行4个路面结构层间2015年5月14日至6月1日温度场实测,研究全透水人行道对海绵体城市建设的有效性。通过对晴天、阴天、雨天模型内部温度场分析可得全透水人行道可有效降低高温时路面温度,升高低温时路面温度;通过比尺模型温度场与沥青路面温度场及实际温度比较,可得全透水人行道在高温时可有效缓解城市热岛效应,下雨时其强大的储水能力使水分蒸发降低路表高温,提高行走舒适性。
On the basis of determining permeable pavement material mixture ratio and layer thickness,scale model is made and the temperature fields of 4 layer of pavement structure between May 14 to June 1 in 2015 are measured,the effectiveness of permeable pavement on sponge city construction are researched. Through the analysis on internal temperature field of the model in the sunny,cloudy and rainy days,permeable pavement can effectively reduce the pavement temperature at high temperature,elevated pavement temperature at low temperature; by comparison of temperature field of the scale model and the actual asphalt pavement,it can be concluded that permeable pavement in high temperature can effectively alleviate the urban heat island effect,when it rains it can storage water powerfully,evaporation of water can reduce road surface temperature,improve the walking comfort.
