Abstract: In view of the multi factor influence problem in the comprehensive vulnerability assessment of urban earthquake disasters combined with the complex internal characteristics of urban system based on the pressure state response model, the comprehensive vulnerability index system of urban earthquake disasters is constructed from seven aspects: natural factors, human factors, lifeline system, social status, economic status, engineering seismic capacity and recovery capacity. The urban vulnerability is evaluated by establishing the comprehensive vulnerability evaluation model of urban earthquake disaster, and the best projection direction of projection pursuit evaluation model is sought by using accelerated genetic algorithm. Combined with the evaluation index value, the projection characteristic index value of the evaluation sample is determined. Taking 12 cities in Gansu Province as an example, the comprehensive vulnerability state of cities is determined by the above model, and the main factors influencing the earthquake vulnerability of cities are analysed according to the results, which provides the basis for decision makers to make earthquake prevention and disaster reduction planning.
