城市轨道交通灾害性天气的定义、分类及研究方向

Definition and Classification of Hazardous Weathers on Urban Mass Transit

阐述了灾害性天气对城市轨道交通的影响及其相关研究的重要性和必要性。综述了国内外相关问题的研究进展。在此基础上,对城市轨道交通灾害性天气作了定义,界定了城市轨道交通17种灾害性天气,并对其进行了分类。指出了今后城市交通灾害性天气研究的主要方向,为今后深入研究城市轨道交通灾害性天气的发生机理及影响规律,以及建立高效的城市轨道交通灾害性天气预防系统奠定基础。

Hazardous weathers have great influence on UMT and it is important to make a research on them. Th s paper discusses the definition of hazardous weathers which interfer urban mass transit seriously, and lists 17 kinds of main hazardous weathers, argues that an effective weather forecast system shah be established on the basis of a thorough study of the mechanism ＆ patterns of hazardous weathers.
