Cloud model urban earthquake hazard risk assessment method and device and storage device

Abstract

The invention provides a cloud model urban earthquake hazard risk assessment method and device and a storage device. The method comprises the steps of determining an urban earthquake hazard risk indicator factor system; layering the urban earthquake hazard risk indicator factor system; constructing a judgment matrix for urban earthquake hazard risk indicator factors belonging to the same layer; building a cloud model for each element of the judgment matrix; calculating a weight cloud model by using the cloud models of the elements; building a membership cloud model through a reverse cloud generator by using historical sample data of the earthquake as cloud droplets; constructing a relationship matrix by using the hazard indicator factors and the corresponding membership cloud model; and performing fuzzy synthesis by using the relationship matrix and the weight cloud model to obtain an assessment cloud model. The cloud model urban earthquake hazard risk assessment device and the storage device are used for implementing the cloud model urban earthquake hazard risk assessment method. According to the invention, the urban earthquake hazard grade can be assessed more visually and more accurately.

Description

technical field [0001] The invention relates to the fields of artificial intelligence, computer algorithms, and disaster risk assessment, in particular to a cloud model city earthquake hazard risk assessment method, equipment and storage equipment. Background technique [0002] With the acceleration of urban development, high-density urban buildings and population aggregation have brought new challenges to urban development and comprehensive management. Once a destructive earthquake occurs in a city, it will definitely pose a great threat to population, economy and social stability. The current domestic and foreign methods of urban earthquake hazard risk assessment are mainly based on historical strong earthquake data, fitting mathematical models, and assessing earthquake hazard risk. However, large direct earthquakes that occur in cities are extremely rare, and it is difficult to collect enough historical earthquake damage data to fit the earthquake hazard assessment model...

However, large direct earthquakes that occur in cities are extremely rare, and it is difficult to collect enough historical earthquake damage data to fit the earthquake hazard assessment model

Some scholars also use the method of fuzzy comprehensive evaluation to evaluate the urban earthquake risk, but the traditional fuzzy comprehensive evaluation method involves a large proportion of experts, and the evaluation results are affected by the subjective factors and personal experience of experts.
