摘要:
结合天津市的自然地理环境,归纳了天津地区地震灾害的分布特点; 考虑地震灾害下人员行为及其影响因素,总结出3种典型避难行为规律。在选取安全合理的应急避难场所与考虑灾区道路网络信息的基础上,分别采用静态与动态Dijkstra算法,对天津市某居民小区至长虹公园避难场所的最佳避难路径进行研究。结果显示:2种方法计算获得的最佳避难路径完全一致,由居民点到安置点的最短路径长度为3 433 m,最短耗时为18.93 min,说明使用Dijkstra算法可为城市灾害避难路径选择与应急预案制定提供必要的方法基础与应用依据。
Abstract:
In order to avoid the loss of life and property caused by earthquake disasters,it is particularly important to plan the route of urban emergency evacuation in advance.By analyzing the natural and geographical environment of Tianjin City,the spatial distribution characteristics of earthquake disasters in Tianjin and three typical laws of evacuation behavior are both summarized considering human behavior and influencing factors during an earthquake.On the basis of a safe and reasonable selection on emergency shelter and the road network information in the disaster area,the static Dijkstra algorithm and the dynamic Dijkstra algorithm are respectively used to study the optimal evacuation route from one residential community to Changhong Park,an emergency shelter in Tianjin based on the road network information in the disaster area.It is shown in the results that the optimal evacuation route calculated by the static Dijkstra algorithm is exactly the same as the one obtained from the dynamic Dijkstra method,with the length of the shortest route from the residential area to the resettlement site of 3 433 meters and the shortest time of 18.93 minutes.It is indicated that the Dijkstra algorithm can provide the necessary method and application basis for the selection of urban disaster evacuation route and the formulation of emergency plan.
