浅析城市道路人行道的海绵化设计

摘要:

在面临迅速的城市化和极端天气这两大挑战的情况下,我国正采取一种新策略：将城市变成巨大的“海绵”,城市“海绵化”改造被提上建设日程,促进雨水资源的利用和生态环境保护的“海绵城市”建设正日益受到重视。海绵城市对于系统解决城市发展中的水问题,具有举足轻重的意义。本文参照了国家海绵城市建设第一批试点城市萍乡市的建设经验,并结合相关规范、标准和图集,因地制宜地进行了人行道的海绵化设计,但国内海绵工程设计及实施方案仍在摸索当中,本文的设计理念可供后续低影响开发建设项目提供参考价值。

Abstract:

SFacing the two challenges of rapid urbanization and extreme weather, China is adopting a new strategy: turning the city into a huge "sponge". The transformation of the city into a "sponge" has been put on the construction agenda. The construction of a "sponge city" that promotes the utilization of rainwater resources and ecological environment protection is receiving increasing attention. Sponge city plays an important role in systematically solving the water problem in urban development. This paper refers to the construction experience of Pingxiang City, the first batch of pilot cities for the construction of national sponge cities, and combines relevant specifications, standards and atlas to carry out the sponge design of sidewalks according to local conditions. However, the design and implementation scheme of sponge engineering in China are still being explored. The design concept of this paper can provide reference value for subsequent low impact development project and construction.
