新疆拟建铁路沿线雪风灾分区和致灾性分析OA北大核心CSCD
Snow and Wind Disaster Zoning and Catastrophability Analysis of the Planned Railway in Xinjiang
对1990 - 2000年新疆铁路沿线地区220个大风灾害日和2000 -2010年300个大(暴)雪日灾情进行了分析,以1961-2008年年均冬季最大雪深、1961 - 2010年年均最大风速和致灾性大风日数及承灾体脆弱性作为铁路沿线雪风灾评价指标,基于GIS空间分析对拟建铁路沿线地区的雪风灾进行了区域划分和致灾性定量分析.结果表明:①冬春季是铁路沿线雪灾高发季.拟建铁路阿勒泰-富蕴段、塔城-额敏段为重雪灾区.在铁路弯道设计、防风墙建设方面应…查看全部>>
In this paper, 220 strong wind disasters occurred in 1990 ~2000 and 300 snow disasters occurred in 2000 - 2010 in the areas along the railway are analyzed. Average annual maximum snow depth in winter during 1961 and 2008, average annual maximum wind speed and average annual number of days during 1961 and 2010 and the vulnerability of hazard-affected bodies are used as the index to evaluate the degree of snow and wind disasters along the railway. Snow and win…查看全部>>
