概括

中国的试点海绵城市 (SPC) 旨在管理城市的雨水,但有些城市仍在淹水. 本研究评估了SPC的性能,确定了进口模型和被忽视的连接等局限性,并提出了更好的城市洪水控制的当地解决方案.

科学领域:

环境科学环境科学
城市规划城市规划
水文学水文学

背景情况:

城市洪水是全球面临的关键挑战,中国快速城市化加剧了这一问题.
中国于2013年启动了海绵城市计划 (SPC),以加强城市雨水管理.
尽管实施了SPC,但几个试点城市仍面临洪水问题.

研究的目的:

系统地评估中国试点海绵城市 (SPC) 在不同气候条件下的表现.
识别和分析阻碍当前SPC实施有效性的局限性.
为改善中国城市雨水管理提出解决方案.

主要方法:

在可变的气候条件下对SPC进行系统性绩效评估.
对实施挑战的分析,包括模型采用和水文连接.
海外模式与本地化方法的比较评估.

主要成果:

目前的SPC实施面临挑战,原因是采用了非本地模型,并没有充分考虑当地水域特征.
在大多数SPC项目中,忽视邻近的水域之间的水文连接是显著的限制.
尽管计划实施,但一些SPC仍在经历城市洪水.

结论:

开发适合中国特定条件的本地化模型对于有效的雨水管理至关重要.
解决SPC实施中的局限性可以导致更有弹性的城市环境.
未来的研究应该集中在具有成本效益的设计,效率优化和地下水影响评估上,以提高城市的抗洪能力.

Design Example: Sustainability in Concrete Building

Design Example: Sustainability in Concrete Building

As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
