Abstract

The embodiment of the invention provides an urban lifeline risk assessment method and device. The urban lifeline risk assessment method comprises the steps: obtaining initial risk information in a to-be-assessed region, wherein the initial risk information comprises a plurality of disaster types and initial risk features corresponding to the disaster types; determining coupling risk information among a plurality of disaster types based on the initial risk information; determining comprehensive risk information in the to-be-evaluated area based on the initial risk information and the coupling risk information; and based on the comprehensive risk information and the disaster response capability information, determining final comprehensive risk information in the to-be-evaluated area. According to the urban lifeline risk assessment method provided by the embodiment of the invention, the disaster types and the coupling disaster types associated with the disaster types are integrated to perform risk assessment on the urban lifeline, so that the assessment range is expanded. The method is more in line with objective reality, and the assessment accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of city safety risk level assessment, and more particularly, to a method and device for city lifeline risk assessment. Background technique [0002] The urban lifeline is a network of public works that guarantees the production and life of urban residents and maintains the basic functions of the city, mainly including electricity, gas, water supply and drainage, heat, transportation and communication systems. With the improvement of modernization and the expansion of city scale, cities rely more and more on lifeline systems. The safety of lifeline systems directly affects the normal operation of urban functions, and the importance of urban lifeline system safety is becoming increasingly prominent. [0003] At present, most of the risk assessments of urban lifelines are based on a single type of disaster, without taking into account the relationship between different types of disasters, resulting in i...
