Embodiment Construction

[0072] The present invention will be further described below in conjunction with accompanying drawing:

[0073] see figure 1 with figure 2 :

[0074] An automatic judgment method for the safety risk of the road tunnel operating environment, starting from the comprehensive operating environment of the tunnel in four aspects: the road environment index, the traffic operating environment index, the traffic engineering facility environmental index and the climate environment, and using the Delphi method to extract the road tunnel operating environment. The main evaluation indicators are analyzed by sensitivity analysis, the evaluation index system of highway tunnel operation environment is established, the weight of each evaluation index is determined by AHP method and entropy weight method, and the safety evaluation of expressway tunnel operation environment is carried out by comprehensive fuzzy evaluation method.

[0075] further, such as figure 1 As shown, a method for auto...

Abstract

The invention discloses a highway tunnel operation environment safety risk automatic judgment method. The highway tunnel operation environment safety risk automatic judgment method, starting from comprehensive tunnel operation environments in four major aspects, that is, road environment index, traffic circulation environment index, traffic engineering facility environment index and climatic environment, extracts main evaluation index of the highway tunnel operation environment through a Delphi method, carries out sensitivity analysis on the evaluation index, establishes a highway tunnel operation environment evaluation index system, determines weight of each evaluation index through an AHP method and an entropy weight method, and carries out safety evaluation on the highway tunnel operation environment through a fuzzy comprehensive evaluation method.

Description

technical field [0001] The invention belongs to the field of risk assessment of road tunnels, in particular to an automatic judgment method for safety risks of road tunnel operating environments. Background technique [0002] Tunnels play an important role in improving route alignment, shortening mileage, improving operating efficiency and protecting the environment. It is a relatively economical engineering solution for expressways passing through mountainous and hilly areas. At present, experts and scholars at home and abroad have conducted a lot of research on the tunnel safety evaluation index system and methods from the aspects of traffic flow theory, aerodynamics, and acoustic theory, and have achieved many research results. These research results have promoted the development of basic theories in the process of safe operation of highway tunnels. However, in the process of safety evaluation, the selection of evaluation indicators is often limited to qualitative and pri...
