极端天气下雨水系统改造措施对雨洪的控制效果研究极端天气下雨水系统改造措施对雨洪的控制效果研究

摘要：随着城市化的进步，城市建设规模逐渐扩大，人口数量大量增加，城市排水难以满足城市化的需求。同时，全球气候变化日益严峻，极端天气频繁发生。例如强降雨导致的洪水往往给城市带来沉重的损失。因此，对城市排水系统的完善和改造迫在眉睫。本文结合国内外有关城市雨水系统的控制和治理方案，对新型城市雨水系统进行了探讨，通过仿真实验和实际工程应用的形式，研究了极端天气下雨水系统改造措施对雨洪的控制效果。本文通过对2010年9月9日发生在中国合肥市伏波山路甲段一次暴雨灾害的调查，抽象出城市雨水系统改造的意义和迫切性，并探讨了目前城市雨水系统的缺陷和不足。基于不同城市雨水系统改造措施的实际效果，本文提出了一些行之有效的城市雨水系统改造方案，并靠实验和模拟验证了这些方案的可行性和有效性。研究表明，利用新型城市雨水系统和改造措施，可以有效地控制和减少极端天气下的雨洪灾害，达到城市治理、环境保护和健康发展的目的。
