Evaluation of runoff control efficiency of permeable asphalt pavement under the sponge city concept
海绵城市理念下透水沥青路面径流控制效能评估

摘要

海绵城市理念强调通过自然方式调控雨水径流，透水沥青路面作为其核心技术之一，对径流控制具有重要作用。本研究旨在评估透水沥青路面对城市雨水径流控制的效能，分析其在不同降雨条件下的表现。通过实验与模拟结合，本文探讨了透水沥青的透水性、渗透能力及其在城市水环境中的作用，评估了其对减少地面径流、提升雨水利用效率及改善城市内涝现象的效果。研究结果表明，透水沥青不仅能有效减少雨水径流，还能缓解城市排水系统的压力，为海绵城市建设提供了一条有效的道路。

Abstract

The sponge city concept emphasizes regulating stormwater runoff through natural means. As one of its core technologies, permeable asphalt pavement plays a crucial role in runoff control. This study aims to evaluate the efficiency of permeable asphalt pavement in urban stormwater runoff control and analyze its performance under different rainfall conditions. By combining experiments and simulations, this paper discusses the water permeability, infiltration capacity of permeable asphalt, and its role in the urban water environment. It assesses the effects of permeable asphalt on reducing surface runoff, improving stormwater utilization efficiency, and alleviating urban waterlogging. The research results show that permeable asphalt can not only effectively reduce stormwater runoff but also alleviate the pressure on urban drainage systems, providing an effective approach for sponge city construction.
