AGF method for evaluating use performance of runway pavement of highway based on safe use of aircraft

Abstract

The invention discloses an AGF method for evaluating the use performance of the runway pavement of a highway based on the safe use of an aircraft. According to four indexes, namely the pavement surface condition, the flatness, the anti-sliding performance and the bearing capacity, of asphalt pavement use performance comprehensive evaluation, a factor set O of a pavement evaluation index system evaluation object is constructed, a judgment matrix A is constructed, an index weight set W is calculated, the maximum characteristic root of the n-stage judgment matrix A is set as lambdamax, a consistency index CI is defined, a consistency ratio CR is calculated, and the total ranking weight, relative to the target layer, of all the layers is calculated; a gray method is used for calculating the grey weight value R, a weighting subset W and a single factor fuzzy subset R are used for compound operation to obtain a fuzzy synthetic evaluation matrix B, and an evaluation result M is calculated, wherein the result is excellent when M is more than or equal to 7.80, the result is good when M is more than or equal to 7.15 and less than 7.8, the result is just well when M is more than or equal to 6.60 and less than 7.15, and the result is poor when M is less than 6.60. The AGF method has the advantage that a quantitative judgment standard can be provided for the safety performance of the runway of the aircraft.

Description

technical field [0001] The invention belongs to the technical field of road aircraft runways, and relates to an AGF method for evaluating the use performance of road runway pavement based on the safe use of aircraft. Background technique [0002] During the long-term use of highway airstrips, the road surface is gradually changed (damaged) by the long-term effects of unfavorable factors such as load and natural environment, which not only endangers the normal vehicle driving or the safety of aircraft use, but also may cause the road to be unable to be used in emergencies. track. However, there is no uniform evaluation method and standard for the performance of highway runway pavement in our country. In order to solve the evaluation problem of highway runway use, based on the analytic hierarchy process, gray relational analysis method and fuzzy set theory of pavement evaluation, based on the basic requirements of safe use of aircraft, based on the field test and calculation ...
