Abstract
In the light of factors influencing highway construction safety that have characteristics of fuzziness and uncertainty, combined with the principle of close degree in fuzzy mathematics, a fuzzy grey connection degree is put forward. The evaluation model based on the fuzzy grey relational analysis theory is established and the construction safety evaluation index system is constructed, the weight of each index is determined by Analytic Hierarchy Process (AHP) and the connection degree is also calculated, and then the rank of evaluated highway construction sites is obtained. It is shown that under the condition of mastering the inspection data of actual construction sites, good results can be achieved through application of the model.
