Research On Quantitative Assessment Method And Application Of Fire Risk In Urban Areas

The level of urban fire risk is directly related to whether a city can achieve the harmonious development of economy,society and fire safety,scientific and reasonable assessment of the level of urban fire risk is of great significance to the urban fire prevention and control work.In this paper,the quantitative method and application research of urban fire risk assessment were carried out to scientifically evaluate the adaptability of fire protection work and social development,so as to provide scientific basis for establishing the industry standard of fire risk assessment in urban areas.The main research work and results are as follows:(1)Based on the overall situation of fire risk assessment in urban areas,a fully quantified urban area fire risk assessment index system is constructed,the benchmark values of each evaluation index are determined,and all indicators are scored,thus a fire risk assessment model based on the fully quantified index system is established.(2)The fire risk of A City is comprehensively evaluated through the established evaluation index system,and the fire risk is relatively high,which reflects the actual situation of fire risk in A City in recent years,and verifies the practicality,objectivity and standardization of the evaluation index system.At the same time using the multiple regression analysis and principal component analysis to fire data of longitudinal analysis in recent years,and establish a prediction model of fire occurrence number,the regression model can better match the original data.(3)Based on the analysis of association rules and the geographic information system,the fire occurrence potential of 60 areas in A City was studied,which provided a reference for the rational allocation of fire rescue forces.Carry out horizontal comparative study on the current situation of fire safety in similar cities,analyze the possible new problems of fire safety in the future development process of A City based on the fire problems experienced by similar cities,and provide guiding opinions for urban fire protection work,for the comparative study of fire risk assessment Theapplication has been usefully explored.
