Abstract

The invention discloses a rail transit tunnel operation period safety evaluation method, a system and a storage medium, belongs to the technical field of rail transit, combines mathematical theory with engineering practice, can make up for the defects of traditional engineering experience safety analysis, more accurately and conveniently serves a rail transit tunnel, and improves the safety of therail transit tunnel. The method comprises the following steps of obtaining all disease parameter data in the whole rail transit tunnel; performing grid division and grid sorting on the rail transit tunnel structural plane, and extracting grid parameters; establishing a rail transit tunnel operation period safety evaluation hierarchical structure model, wherein the hierarchical structure model presents a hierarchical structure and is composed of an index layer, a middle layer and a target layer; determining a weight value between the layers; a variable weight vector function is constructed, aquaternion linear equation set is established, variable weight vector function parameters are determined through a mathematical calculation method, the variable weight vector function is obtained, finally, the variable weight function is constructed, data is visualized through a program, and a rail transit tunnel overall structure safety evaluation chart is obtained.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a safety evaluation method, system and storage medium of a rail transit tunnel during an operation period. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The main form of underground transportation is urban rail transit, which has become the main force of important traffic in major cities in the world. However, rail transit also has shortcomings such as closed environment, small space, and excessive flow of people within a certain period of time, which will be greatly restricted when evacuating and escaping. In such a situation, it is necessary to predict the safety performance of the tunnel in advance and make an emergency plan in time It has become an indispensable means, so it is necessary to propose an effective safety evaluation ...

However, rail transit also has shortcomings such as closed environment, small space, and excessive flow of people within a certain period of time, which will be greatly restricted when evacuating and escaping. In such a situation, it is necessary to predict the safety performance of the tunnel in advance and make an emergency plan in time It has become an indispensable means, so it is necessary to put forward an effective safety evaluation method for the operation period of rail transit tunnels

[0004] The inventors have found that there are multiple characteristic parameter factors such as cracks, cavities, water leakage, and deformation that affect the safety of rail transit tunnels. The difference is that each characteristic parameter has different weights for rail transit tunnels, and the weights change with the value of each characteristic parameter. The traditional evaluation method is too artificial, mainly based on engineering experience, and does not consider each characteristic. The weight change relationship between parameters, the weight changes according to the state vector of the factor, better reflects the impact of the state change of the corresponding factor on the decision-making system
