Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation examples, and an urban fire risk assessment is carried out for a certain city in Hubei Province.

[0029] In an embodiment, an urban fire risk assessment method based on a reference value is characterized in that it includes the following steps.

[0030] The first step: according to figure 1 Establish an index system for urban fire risk assessment, which includes four levels: target level, first-level indicators, second-level indicators and third-level indicators.

[0031] The target layer includes the level of urban fire risk and the level of urban fire prevention and control. The level of fire risk includes the risk characteristics of urban areas and the characteristics of fire hazard in places. The level of urban fire prevention and control includes the level of fire prevention, public fire-fighting infrastructure and fire fighting and resc...

Abstract

The invention relates to the technical field of fire fighting fire disaster prevention, in particular to an urban fire disaster risk estimation method based on a reference value. The method is characterized in that the method comprises following steps of step 1, establishing an urban fire disaster risk estimation index system, wherein the urban fire disaster risk estimation index system comprisesa target layer, a first grade index, a second grade index and a third grade index; step 2, calculating the weight of each grade index relative to the upper grade index and calculating the total weightof each index relative to the target layer; step 3: calculating the specific score of each grade index; and step 4: determining the grade of the target layer, i.e., the grade of the urban fire disaster risk. According to the invention, normalization, objectivity and comparability of the urban risk estimation can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of fire prevention and fire protection, in particular to an urban fire risk assessment method based on a reference value. 【Background technique】 [0002] In recent years, with the development of science and technology, scholars from all over the world have actively explored and tried usefully on urban fire risk assessment, and proposed various evaluation systems. So far, my country has not yet promulgated the standardization of urban fire risk assessment. systems and methods. However, in the urban fire risk assessment system proposed by scholars from various countries, there are generally the following problems that need to be solved urgently, such as: the selection of indicators is too macroscopic, the investigation of fire characteristics in typical urban places is ignored, the unique fire risk of a specific city is not specified, and the new Fire protection policy is not involved in the indicator system...
