Abstract
Snowdrift disaster is a key and difficult point in route selection and design of Karamay-Tacheng railway line. Study on the characteristics of snowdrift disaster to effectively avoid and reduce disaster sections has important theoretical and practical significance in route selection and snow hazard prevention. Based on existing meteorological data, site investigation and simulated results of numerical weather forecast model and meteorological modules in atmospheric pollution model, it is concluded that the prevailing wind direction is east-bond and southeast-bond in winter, and west-bond and northwest-bond in summer with obvious seasonal alternation; strong east wind and west wind appear in succession; moreover, the wind in winter is generally stronger than that in summer. Therefore, the snowdrift in winter is the key point for snow disaster prevention. Using satellite image and regional climate simulation analysis brings to a conclusion that the south line scheme Laofengkou scheme) is 24. 2km longer with sections with possible snowdrift and higher frequency than the north line scheme (Mayitasi scheme).关键词
