滨海地区建筑与小区海绵城市设计的反思与优化

Reflection and Optimization of Building and Sub‑district Sponge City Design in Coastal Area

厦门市从2015年开始持续推进海绵试点城市建设,结合近几年厦门市海绵城市方案设计联合技术指导工作,以及建设项目海绵城市事中事后的巡查和验收,对建筑与小区海绵城市设计在指标确定、方案设计和景观衔接等方面存在的问题进行分析和反思,提出进一步的优化方案。主要从目标指标、汇水分区划分、海绵设施布局、调蓄容积计算,以及溢流雨水口、透水层、碎石层设计等方面进行优化,可为沿海城市建筑与小区海绵城市建设提供科学支撑。

Xiamen has continued to promote the construction of sponge pilot city since 2015.This paper analyzed and reflected on the problems in the determination of indicators,scheme design and landscape connection in the design process of sponge city in buildings and sub‑district,and proposed further optimization scheme based on the joint technical guidance work of Xiamen sponge city project design in recent years,and the inspection and acceptance of construction projects during and after the event of sponge cities.The optimization was mainly carried out from the aspects such as target indicators,catchment area zoning,sponge facility layout,regulation and storage volume calculation and design of overflow inlet,permeable layer and gravel layer,which aimed to provide scientific support for the construction of building and sub‑district sponge city in coastal cities.
