城市道路设计中的海绵城市设施选型探索

摘要:

近年来，“海绵城市”在全国进行了大量的推广和实践，在城市道路设计中，海绵城市设施主要是对年径流总量控制率和雨水径流污染物削减率进行控制。本文根据理论计算方法，结合建设实例，针对不同路幅、不同纵坡的道路，对海绵城市设施选型进行探索，并提出建议，可为城市道路海绵城市设计提供参考。

Abstract:

In recent years, intensive promotions and practices of sponge city construction has been going on in different cities, in urban road design, sponge city facilities could be utilized to effectively control the total annual runoff control rate and the reduction rate of runoff pollutants. According to the theoretical calculation method and combined with construction examples, this study explores the selection of sponge city facilities for roads with different road widths and longitudinal slopes, and provides forward suggestions, which could offer references for the sponge city design of urban roads.
