北方寒冷地区海绵型城市道路建设适用技术

Applicable Technology for Sponge-type Urban Road Construction in Cold Regions of Northern China

"海绵城市"作为一种设计的新理念,通过组合的方式对雨水进行"渗、滞、蓄、净、用、排"的综合利用,真正地使城市生态环境得到很好的保障,并降低城市开发建设过程中对生态环境的影响。由于北方冬季气候寒冷,季节性冻土层达到1-2米,许多标准的海绵做法和措施在北方并不适用,需要我们探索一种北方寒冷地区特有的海绵城市建设模式。文章以长春市海绵型城市道路设计为例,详细阐述设计方案,提出了北方寒冷地区在海绵城市建设中道路的设计。

As a new design concept,"Sponge City" comprehensively utilizes the "infiltration, stagnation, storage, purification, use and drainage" of rainwater in an integrated way to truly ensure the urban ecological environment and reduce theimpact on the ecological environment during urban development and construction. Due to the cold winter weather in the north and the seasonal frozen soil layer of 1-2 meters, many standard sponge practices and measures are not applicable in the North China. We need to explore a unique sponge city construction pattern in the cold northern regions. Taking the design of sponge-type urban roads in Changchun City as an example,the paper elaborates the associated design planand hopes to provide some ideas for readers.
