【摘要】：利用全國2373個國家級地面氣象觀測站2005—2014年10 min平均風速以及2009—2014年1 h內極大風速資料,基于氣象行業(yè)標準(QX/T 111—2010)中風力對高速公路交通運行影響的等級劃分,選取頻率與強度作為指標構建評價體系,結合熵權法計算致災因子危險性綜合指數,編制全國致災大風危險性評價圖。結果表明,對高速公路交通運行產生影響的致災大風高危險區(qū)主要分布在內蒙古中西部、西藏北部和西部的局部地區(qū)以及新疆阿拉山口、達坂城、三十里風區(qū)與百里風區(qū)范圍內;較高危險區(qū)主要分布在內蒙古中部和西部、甘肅西部、青海西部和南部、新疆西北部和東部以及東部沿海的部分地區(qū);全國其他地區(qū)主要高速公路沿線的致災大風危險性則相對較低。
[Abstract]:The data of average wind speed of 10 min from 2005 to 2014 and the maximum wind speed of 1 hour from 2009 to 2014 are used in 2373 national surface meteorological observatories in China. Based on the classification of the influence of wind force on highway traffic in the meteorological industry standard (QX/T 111-2010), the evaluation system is constructed by selecting frequency and intensity as indicators, and the comprehensive risk index of disaster factors is calculated with entropy weight method. To compile the national hazard assessment map of disaster-induced gale. The results show that the high risk areas of disasters and gales that affect the traffic operation of the expressway are mainly located in the central and western parts of Inner Mongolia, northern and western parts of Tibet, as well as in Alashan pass and Dabancheng, Xinjiang. 30 li wind area and 100 li wind area; The high risk areas are mainly distributed in central and western Inner Mongolia, western Gansu, western and southern Qinghai, northwest and eastern Xinjiang, and parts of the eastern coastal areas. Other areas of the country along the main highway disaster risk is relatively low.
