Abstract

The invention discloses a highway tunnel health status dynamic evaluation method based on the variable fuzzy set theory. The method comprises the steps of constructing a highway tunnel health status evaluation index system with lining fissures, lining strength, lining thickness, corrosion of reinforcement, lining deformation, back cavities, pavement distress, harmful gas and lighting distress as evaluation indexes as well as the qualitative and quantitative criterion of the evaluation grade and each evaluation index of highway health status; and through repeated and regular detection of the highway tunnel evaluation indexes by a tunnel diagnosis and fast repairing integrated car and based on the variable fuzzy set theory, determining highway tunnel detection node health status values and the health status deteriorating speed mean value and establishing a highway tunnel health status dynamic evaluation model by means of repeated detection data of the highway tunnel health status evaluation indexes and the criterion of the evaluation grade and each evaluation index of the highway health status. The highway tunnel health status dynamic evaluation method based on the variable fuzzy set theory not only achieves objective evaluation of the highway tunnel health status, but also can be used for dynamic prediction of the highway tunnel health status.

Description

technical field [0001] The invention belongs to the technical field of road health status evaluation, and in particular relates to a dynamic evaluation method for the health status of road tunnels in operation based on variable fuzzy set theory. Background technique [0002] Scientific and systematic evaluation and prediction of the health status of highway tunnels is the premise of correct decision-making for highway tunnel disease control. At present, there are deficiencies in the existing evaluation methods of road tunnel health status in China: 1) The selection of evaluation indicators is not scientific enough, and the independence of evaluation indicators is poor, and there is a certain correlation; 2) It is not predictable, and the current evaluation method of road tunnel health status Generally, there is no prediction function, and the prediction of tunnel disease development is still based on experience. Therefore, it is imminent to study the dynamic evaluation meth...
