Abstract

Seismic secondary fires are the main earthquake secondary disasters, and rapid post-earthquake fire risk assessment helps to take effective measures to reduce the occurrence and spread of fires and minimise casualties and property losses. In this paper, a method of monitoring and rapid assessment of earthquake secondary fire risk based on directed graph model is used to determine the fire spread paths between single buildings by on-site investigation and simplified calculation of the buildings in the macro-earthquake epicentre region of the Luding earthquake, and different fire spread partitions by combining with node traversal algorithms to draw a directed graph model of the secondary fire spread in the earthquake in Caiyang Village. By calculating the fire spread risk under 348 fire scenarios and the loss in 71 fire spread zones, it was concluded that the fire spread risk is higher in building nodes 120, 150 and 340, and the fire spread loss is higher in fire spread zones 24, 30, 48, 56, 60, 61, 69 and 71, and it is recommended to strengthen the key fire safety inspection of the above buildings and building zones. Monitoring.
