Embodiment Construction

[0031] Such as figure 1 shown. The present invention uses the fire risk parameter R' to evaluate the fire risk of buildings, and the calculation method of the fire risk parameter R' is as follows:

[0032] R ′ = ϵ · ( A + B ) C - - - ( 1 - 11 )

[0033] Among them, A is the inherent risk of the building; B is the risk of people in the building; C is the ability to control the risk, including the ability of the building itself to control the risk and the ability of the fire brigade to control the risk; ε is the impact factor of the building on the surrounding area, such as figure 2 shown.

[0034]The values ​​of A, B, C, and ε are all transformed into dimensionless numbers through dimension...

Abstract

The invention discloses a fire disaster high-risk unit fire risk assessment method based on control force analysis. Quantitative evaluation is conducted on fire risks of a building by a formula. Factors relative to property loss in a factor evaluating and calculating method information retrieval (IR) are integrated into GR. Risks caused by a fire disaster are divided into two aspects which are respectively building inherent risks A and risks B of people in the building, and control ability C of people to a potential fire disaster is taken into account. The control ability C comprises two aspects which are respectively the ability to enhance risk resisting ability of the building by adopting a fire-proof design and allocating fire-fighting equipment, and the rescue ability of a fire protection force, and the two aspects are indicated by the ability E to control the risks by the building and the ability gamma Sigma Z H L to control the risks by the fire protection force. The actual fire risks of the building is a value obtained by (A+B)/C, and the risks emphasis on physical loss, and therefore a factor epsilon which indicates the influence of the building on the periphery is used so as to show non-physical loss possibly brought by the fire disaster of the building.

Description

technical field [0001] The invention relates to the technical field of fire risk assessment, in particular to a fire risk assessment method for high-fire risk units based on control force analysis. Background technique [0002] Fire risk refers to the consequences of a potential fire event and the probability of its occurrence. Among them, the consequences generally include casualties, property damage, system operation interruption, environmental damage, etc. The probability of occurrence can be estimated by the number of occurrences of the considered loss situation within a certain time interval. [0003] Fire risk assessment methods include empirical analysis, system anatomy analysis, logical derivation analysis, human error analysis and other types according to the method structure; according to the form of assessment results, they can be divided into qualitative, semi-quantitative and quantitative fire risk assessment methods. The following is a brief introduction to t...
