Abstract and Keywords

Abstract: In order to study the overall rainwater retention capacity of permeable asphalt pavement during the long-term service, this paper takes Weiba Road in Yingshang County as research object. The storm water management model (SWMM) model of the road was established, and the rainwater retention capacity of the pavement in wet, flat and dry years was analyzed through the design of short-duration rainfall pattern. A simulation analysis was conducted on the comprehensive rainwater retention effect of the pavement during the designed service life. The results show that the total annual runoff control rates of the pavement in flat and dry years reach 72.14% and 75.37%, respectively, showing strong rainwater retention capacity. The rainwater retention capacity of the pavement is slightly lower in wet years. Except for extremely wet years, the total annual runoff control rate in wet years is only slightly lower than the target rate, which is less than 3%. The total average annual runoff control rate of the pavement during the designed service life is 66.34%, which meets the requirements of sponge city construction.

摘要: 为研究透水沥青路面长期使用过程中的整体滞蓄雨水能力,文章以颍上县纬八路为例,建立研究道路的暴雨洪水管理模型(storm water management model, SWMM),通过设计短历时降雨雨型剖析了路面在丰水、平水、枯水年3种情景下的滞蓄雨水能力,并对路面在设计使用年限内的综合滞蓄雨效果进行模拟分析。结果表明:路面在平水年以及枯水年下年径流总量控制率分别达到72.14%和75.37%,表现出较强的雨水滞蓄能力;丰水年下路面的雨水滞蓄能力略低,除了特丰水年外,丰水年间的年径流总量控制率仅略低于目标年径流总量控制率,在3%以内;路面在设计使用年限内总平均年径流总量控制率为66.34%,符合海绵城市建设要求。
