The paper discussed the harm types and cause of overload vehicles on all kinds of bridges,and proposed some advice for reference.

According to the types of the overload vehicles and the requirements for the bridge-passing,this paper analyzes on the vehicle overload transportation in Shanxi Province,and puts forward some measures for the management of the overload vehicles and for the reinforcement of the bridges.

In accordance with the bridge damage question in view of the overload vehicles,analyzed the damage form when the overload vehicles act on the different structure bridge,given the general method which the bridge damage investigates and examines,discussed the bridge structure damage preventive measure,and given the preliminary discussion on the prevent and reinforcement.
