The purpose of this paper is to study stormwater management potential of new permeable pavement with subsurface micro‐detention storage (PPDS) at low‐speed residential suburban area. The main features incorporated permeable pavement of a hollow micro cylinder precast structure with solid hexagon precast concrete as top and bottom covers. The purpose of hollow micro detention design is for rainwater holding and void between the sets is for self‐drying through the side and bottom seepage during rain. The hydrological parameters were obtained from laboratory rainfall simulator experiment. The performance was evaluated via simulation with Storm Water Management Model (SWMM). The outcomes from the physical model matched well with SWMM. A case study was then developed to assess the hydrological impact of PPDS with the existing condition and other types of permeable pavements. Significant variance was observed, where PPDS displayed its best hydrological performances for stormwater management with the presence of subsurface detention storage.

地下预制微型滞留池对透水路面的水文影响评估

本文的目的是研究低速郊区郊区具有地下微滞留存储器（PPDS）的新型渗透性路面的雨水管理潜力。主要特征包括空心微圆柱体预制结构的渗透性路面，以实心六角形预制混凝土作为顶盖和底盖。中空微滞留设计的目的是为了保持雨水，而套件之间的空隙是为了在下雨时通过侧面和底部的渗水自动干燥。水文参数是从实验室降雨模拟器实验获得的。通过使用雨水管理模型（SWMM）进行仿真来评估性能。物理模型的结果与SWMM很好匹配。然后进行了案例研究，以评估PPDS在现有条件和其他类型的渗透性路面的水文影响。观察到了显着的差异，PPDS在地下蓄水库的存在下表现出了最佳的雨水管理水文性能。
