摘要:
透水砖铺装地面是城市雨水资源综合利用技术中的重要组成部分，硬化地面采用透水砖铺装不仅能够提高下垫面的入渗能力，增加地下水补给量，还可以减少地面积水，改善局部生态环境，在城市雨水控制利用系统中发挥着巨大作用。通过开展人工降雨实验，分析了透水砖铺装的入渗特性和降雨产流规律。结果表明，降雨条件下，透水砖铺装地面入渗过程大致分为3个阶段，其遵循初期雨水全部入渗、铺装结构层饱和后降雨全部产流的规律，铺装结构初期入渗速率与降雨强度有关，稳渗率与土壤、垫层性质及前期含水量有关。同时，进一步提出了基于降雨量、容水量和土壤入渗能力的透水砖铺装地面动态径流系数计算公式。
Abstract:
Permeable brick pavement is an important part of urban rainwater resources comprehensive utilization technology. Permeable brick paving on hardened ground improves the infiltration capacity of the underlying surface, increases the groundwater recharge, reduces the surface ponding, improves the local ecological environment, and plays a prominent role in urban rainwater control and utilization system. This paper analyzed the infiltration characteristics of permeable brick pavement and the law of rainfall runoff through artificial rainfall experiment. The infiltration process of permeable brick pavement could be generally divided into three stages during the process of rainfall, which followed the law of initial rainwater totally infiltrating and rainfall completely changing into runoff after the saturation of the pavement structure layer. The initial infiltration rate of pavement structure was related to rainfall intensity, while the stable infiltration rate was related to properties of soil and underlayer and preliminary moisture content. In addition, the calculation formula of permeable brick pavement surface dynamic runoff coefficient was further proposed based on rainfall, water storage capacity and soil infiltration capacity.
