| 摘 要： | 运用2011年12月至2015年11月河北省11条高速公路沿线156套交通气象监测站资料、142个国家气象站雾灾资料、因雾造成的交通事故和封闭管制资料、高速公路日均车流量、路网密度等资料,基于致灾因子危险性、承灾体空间脆弱性以及承灾体易损性3个方面建立了高速公路雾灾风险区划模型,并绘制河北省高速公路雾灾风险区划图。结果发现:(1)河北北部地区、西部山区、沧州沿海地区的高速公路雾灾风险等级较低,而东部和南部平原地区的高速公路雾灾风险等级较高,可为交通安全管理部门提供一定的参考依据;(2)在相同区域内,局地浓雾多发、交通事故多发、大范围雾日多都可造成高速公路雾灾风险等级升高。

| Abstract: | By using the data from December 2011 to November 2015 in Hebei Province, including the data from 156 traffic meteorological stations along 11 expressways, the fog disasters of 142 meteorological stations, traffic accidents and closing control measures on expressway caused by fog, average daily traffic volume and road network density on expressway, the risk zoning model of fog disaster is established based on the dangerousness of Hazard factors, the spatial fragile and vulnerability of the disaster bodies, and the fog disaster risk zoning map of expressway in Hebei Province is given. The results show: (1) The risk grades of fog disasters on expressways in the northern Hebei Province, the western mountains and the coastal areas of Cangzhou are at the lower level; however, those of fog disasters on expressways in the eastern and southern plains are at the higher level, which can provide a reference for the traffic safety management department. (2) Frequent heavy fog events, traffic accidents and the wide range of fog are the reasons leading to the rising risk grads of fog disasters on expressway. |
