| 摘 要： | 生物滞留带作为一种低影响开发设施在海绵城市建设过程中得到了广泛应用,尤其是道路-生物滞留带组合系统不仅能够有效减少路面径流外排总量,还能降低峰值流量、有效控制雨水径流污染。城市道路路缘石豁口作为连接道路与生物滞留带的关键设施,其水力特征和截流效率计算至关重要。总结了国外城市常见的道路豁口设计计算方法,并结合具体案例分析了不同设计方法的特点,以期对海绵城市建设中城市道路豁口设计计算方法提供参考。

| Abstract: | As an important measure of low impact development ( LID), the biologic-retention facility is widely used in the sponge city construction. In particular, the combination of road biologic retention system could not only reduce the road surface runoff, but also reduce the peak discharge efficiently, and effectively control the rain water runoff pollution. As a key connection between road and bioretention, the calculation of hydraulic characteristics and closure efficiency of the curb inlet is very important. This paper summarized the design methods of common curb inlet used in foreign cities, and analyzed the characteristics of different design methods combined with concrete cases. This study could provide some suggestions for road biologic-retention curb inlet design during sponge city construction. |
