Study on Bayesian network model for evaluation of large-type bridges

Xihoumen bridge has become one of the bridge with worst environment because of nature environment of island and the suspension bridge with king-size. The evaluation for Xihoumen bridge is very important to perform the corresponding maintenance measures for Xihoumen bridge. In the paper, Bayesian network is proposed to the large-type bridges evaluation. Evaluation indexes of the large-type bridges are analyzed. The large-type bridges evaluation model based on Bayesian network is created. Xihoumen bridge is employed to testify the feasibility of Bayesian network in the large-type bridges evaluation.
