近年来,随着经济的发展:危险化学品运输变得越来越频繁,这类交通事故也随之上升,造成危险化学品泄漏和污染,严重危害了人民群众的生存环境。例如,2003年7月3日,一辆满载25t液态丁烷的槽车在京珠高速公路长沙县安沙服务区换轮胎时,由于烈日当空,气温过高,急剧膨胀的丁烷气体冲开安全阀门直往外冒,雾状气体从槽车顶部腾空而起,刺鼻的气味迅速扩散。一旦遇有火苗或静电火花,这颗威力无比的“炸弹”将给lkm范围内的生灵及两个加油站造成毁灭性的打击。幸亏报警及时,在公安、消防等部门的全力合作下,经过10个小时的冷却处理,险情终被排除。 相似文献

The article establishes the patterns of urban snow disaster system and disaster chain based on the theory of regional disaster system. The patterns indicate that urban snow disaster is exacerbated mainly through the traffic system. In addition, the paper sets up the vulnerability assessment index system and synthetically vulnerability assessment model of urban snow disaster which are mainly based on traffic system, and applies them in Chenzhou City. The results of assessment indicate that obvious geographical differences exist in the vulnerability of snow disaster bearing bodies: vulnerability of Chenzhou section of the Beijing-Zhuhai expressway is the highest in Chenzhou City, and the southeastern counties are more vulnerable than the northwest region. Furthermore, according to the snow disaster vulnerability dynamic process analysis, the vulnerability of Chenzhou City obviously increased in 2008 winter compared with that in 2007. Finally, the paper presents some suggestions for the locations of the emergency commands and the reserves of relief materials based on the evaluation results, and points out that disaster monitoring and relevant technical level should be strengthened for the minimization of traffic system's vulnerability. 相似文献
