基于海绵城市建设的城市道路优化设计研究

摘要:

我国城市化发展速度不断加快,也带来了城市硬化面积占比增大的问题,在雨季易发洪涝灾害。而海绵城市建设理念可有效提升城市排洪能力,同时可实现径流污染物的净化,现已逐渐得到推广。本文依托上海市城市道路设计方案,以横断面分幅形式及退让区域绿地情况作为控制指标,对四条道路设计方案进行分析；通过评价指标对道路设计成果进行评估；并基于海绵城市建设理念提出优化思路。本文研究成果可为现有城市道路优化设计提供参考。

Abstract:

The continuous acceleration of the development of urbanization in my country has also brought about the problem of an increase in the proportion of urban hardened areas, which is prone to floods during the rainy season. The concept of sponge city construction can effectively improve the city"s flood discharge capacity and at the same time achieve the purification of runoff pollutants, which has been gradually promoted. Based on the urban road design plan of Shanghai, this paper analyzes the four road design plans with the cross-sectional format and the green space of the concession area as the control indicators; evaluates the road design results through the evaluation indicators; and proposes optimization based on the sponge city construction concept Ideas. The research results of this paper can provide a certain reference for the optimization design of sponge city on existing urban roads.
