The invention discloses a traditional village fire scene
cascade failure road
vulnerability assessment method, and relates to the technical field of building group
fire prevention and control and personnel evacuation. The method comprises the following steps: firstly, acquiring
space vector data of traditional village building groups, single buildings and roads, and constructing a building group fire spreading network and a road network; then, constructing a road
vulnerability evaluation system, introducing an
accessibility index to dynamically represent the
road traffic efficiency, and defining the
vulnerability index to quantify the influence of the disaster on the road
system; finally, a multi-layer network
cascade failure
simulation framework is provided, the framework can quantify the dynamic
cascade failure process, and a multi-scene vulnerability thermodynamic diagram is generated to locate a high-
risk area. According to the method, the influence of the traditional village building fire on the road network is fully considered, the fire-road double-layer
coupling network model is established, dynamic quantification is realized, a scientific decision-making tool is provided for the traditional village building fire and the road evacuation risk, and the method has important application value for improving the
toughness of the traditional village.
