【 摘 要 】

The overload and overweight operations of vehicles in expressway are particularly serious in China recently. Research on the extreme maximum value of the vehicle loads is an urgent problem in the bridge design. On the basis of statistical analysis of the WIM data from Yu-Zhan Expressway under toll-by-weight mode in Guangdong Province, the POT probability model of gross weight of the vehicle was established by the extreme value theory. It can predict the probability distribution of operating vehicle loads in any recurrence period. Results showed that the overweight vehicles were not accidental, and there may be heavier vehicles in the future. It is necessary to improve and modify the current toll-by-weight charging policy.
