摘要
借鉴已有气象灾害风险区划相关研究成果,初步探讨高速铁路气象灾害风险分析与区划方法。从气象灾害对高速铁路的影响机理入手,分析筛选出大风、水灾、雷电、低温雨雪冰冻等气象灾害的风险评价因子,构建区划评价指标体系,建立评价模型,分析制定可体现高速铁路沿线气象灾害风险发生时间、空间、强度可能性的风险区划方案,为科学制定沿线气象灾害风险区划提供参考依据。
Referring to the relevant research results of risk zoning of meteorological disasters,we preliminarily explore the risk analysis and zoning methods of meteorological disasters in high-speed railway. Starting from the impact of meteorological disasters on high-speed railway,we analyze the strong winds,floods,lightning,snow and ice and other meteorological disaster risk assessment factors,construct the evaluation index system,establish the evaluation model,and analyze the risk zoning plan that can reflect the occurrence time,space and intensity of meteorological disasters along the railway line,to provide reference for the scientific development of meteorological disaster risk zoning.
