Example Embodiment

[0022] In order to make the above objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Taking a highway in Anhui Province as a research object, the road section is 5km, the number K20 + 000 ~ K25 + 000 is the detection section, combined with the actual road driving background, the highway is mainly medium and heavy transport vehicles, driving The dynamic load is large, and the road repeatedly withces the fatigue load, which is prone to cracks, ruts, pit grooves, etc. The road damage condition and the relevant indicators of the road surface flatness are at a low value level.

[0024] The present invention is based on the road surface condition evaluation model of integrated integrated employment method comprises the following steps:

[0025] Step 1: Build a comprehensive evaluation index system with the road surface condition index as...

Abstract

The invention provides a pavement condition comprehensive evaluation method based on a fuzzy comprehensive evaluation method, which comprises the following steps: analyzing and listing various levels of evaluation indexes which comprehensively represent multi-aspect attributes of pavement use performance and reflect a pavement comprehensive condition, and establishing a pavement condition comprehensive evaluation system based on the various levels of evaluation indexes; utilizing a fuzzy comprehensive evaluation method to determine a factor set and a comment set of the evaluation model on the basis of the pavement condition comprehensive evaluation system; through single-factor evaluation of the factor set, determining membership degree measurement of various factors on various evaluation grades one by one, and building a fuzzy evaluation matrix; introducing a weight distribution set according to different influence degrees of each factor in the factor set on the comment set; and performing fuzzy synthesis operation by using the fuzzy evaluation matrix and the weight distribution set to obtain a road surface fuzzy comprehensive evaluation result vector, and analyzing the road surface fuzzy comprehensive evaluation result vector to obtain a comprehensive and accurate evaluation result of the pavement condition. Defects existing in a current pavement condition evaluation model can be solved, and the reliability and the accuracy of a pavement condition comprehensive evaluation result are improved.

Description

technical field [0001] The invention relates to a comprehensive evaluation method for road conditions based on a fuzzy comprehensive evaluation method. Background technique [0002] Transportation plays an important role in the sustainable development of a country, and the application of scientific methods and innovations in road construction management is conducive to resource conservation and sustainable development. At this stage, the national highway management department mainly relies on the evaluation of pavement technical conditions to understand the actual situation of the pavement, but the current pavement technical evaluation index is only a single comprehensive evaluation index weighted by individual evaluation indicators at all levels, and the comprehensive evaluation index is mapped to the evaluation grade standard interval To achieve a comprehensive evaluation of the road condition. The entire evaluation process neither combines the actual engineering backgrou...
