A Vulnerability Evaluation of Airport Rigid Pavement Based on Strong-Fuzzy Cloud Model
In order to further improve the assessment system for civil airport runway pavements,a new rigid pavement vulnerability evaluation system is developed on the basis of existing technical specifications for pavement evaluation and management.This system comprehensively evaluates the vulnerability of pavements in consideration of both structural and functional aspects.Five representative structural indica-tors and four functional indicators are selected,and their weights within the sub-systems are determined by using entropy weight method.With the aid of an advantage of the prominent ability of the fuzzy cloud e-valuation model in transforming between qualitative concepts and quantitative descriptions,a Strong-Fuzzy Cloud Mode(SFCM)is proposed based on the Extended Cloud Model(ECM).Then,the comprehensive vulnerability assessment model for runway pavements is established.By analyzing the actual pavement in-spection data from a southern airport,the comprehensive vulnerability assessment value for this pavement is determined as 2.277,indicating a high level of vulnerability.The confidence level of the assessment re-sults is close to 1,demonstrating the validity of the calculated results.Furthermore,the assessment result is consistent with the evaluation result(2.123)obtained by using ECM,confirming the reliability of the assessment outcome.The SFCM takes into account the non-conformity of evaluation indicators to the standard normal distribution,constructs skewed distributions,and enhances the fuzziness of interval tran-sitions,whereas the results of assessment conform even more to reality.
