针对我国高速公路建设突发事件应急救援管理的现状,基于协同思想并结合应急管理技术,提出“点-层”辐射的多级响应、逐级控制应急救援模式;以应急物资准备时间、应急救援响应延误时间和应急救援行程时间3个子目标最小为目标函数,建立了高速公路建设突发事件协同应急救援模型;应用格林希尔茨公式动态求解路网中各路段权值参数,得出“节点-节点”路径权值矩阵,并结合Dijkstra算法求解时间最短救援路径,以求得各子目标函数的最优解,并最终确定最优应急救援方案。将该研究成果应用于某高速公路特大桥项目施工突发事件应急救援中,得出其最短救援时间为16.25 min,比原应急预案标准提出的30 min救援时间节省约14 min,表明该研究成果有一定可行性和有效性。
Aiming at the status quo of emergency rescue and management in China’s expressway construction, based on the synergetic thinking and the emergency management technology, a multi-level response of “point-layer ” radiation was put forward to control emergency rescue mode step by step. With emergency material preparation time, Emergency rescue response delay time and emergency rescue travel time of three sub-goals as the objective function, the establishment of a highway emergency response emergency rescue model; Greenhills formula dynamic solution of the road network in the weight parameters of each section, come to “Node - node ” path weight matrix, combined with Dijkstra algorithm to solve the shortest rescue path to get the optimal solution of each sub-objective function, and finally determine the optimal emergency rescue plan. The results of this study were applied to the emergency rescue of construction of an expressway bridge project, and the shortest rescue time was 16.25 min, saving about 14 min compared with the 30 min rescue time proposed by the original emergency plan, indicating that the research results A certain feasibility and effectiveness.
