太原市属于干旱少雨的城市,全年降雨量不及蒸发量的1/3,但是逢雨必淹、逢雨必涝的现象愈演愈烈。城市雨水系统的脆弱与城市快速化发展的矛盾日益凸显,城市内涝成为城市发展的“内伤”。传统设计理论存在的缺陷和建设管理方法的不当是造成城市内涝的主要原因。从技术层面详细分析了太原市城市内涝的成因,并提供了相应的解决对策。
Taiyuan City is a dry and rainy city. The annual rainfall is less than 1/3 of the evaporation, but the phenomenon that every rain must be flooded and every rain is inevitable is getting worse. The contradiction between the fragility of the urban rainwater system and the rapid development of the city has become increasingly prominent, and urban agglomerations have become “internal injuries” of urban development. The flaws in the traditional design theory and the improper construction management methods are the main causes of urban hustle and bustle. From the technical level, the causes of the urban guilt in Taiyuan were analyzed in detail, and corresponding countermeasures were provided.
