1. The principle of bridge reinforcement

1. Before construction, the indicators of the bridge are tested, and the corresponding reinforcement plan is formulated to ensure that the bridge is still in operation during the reinforcement construction period.

2. For some bridges that have been used for a long time, we should reduce the carrying capacity of the old bridge, test these bridges, and implement the reinforcement scheme for the old bridge according to the original design drawings;

3. The bridge should be reinforced according to the actual situation, and the most appropriate and economical reinforcement method should be made.

4. After the bridge is reinforced, it should have real meaning and provide real help for the bridge reinforcement.

2. The significance of bridge reinforcement

1. Improve the safe use of bridges. After reinforcing some old bridges, the safety of the bridge will be improved, and we will be at ease when using it;

2. Improve the bearing capacity of the bridge. The number of means of transportation in our life is increasing, and some bridges in our country can no longer meet the current carrying capacity, so it is urgent to reinforce the design of old bridges;

3. Extend the life of the new bridge. If we strengthen and maintain the new bridges, it will increase the service life of the new bridges and reduce the impact on traffic, and can make reasonable and full use of national resources;

4. Control costs and expenses. If we reinforce and repair the old bridge, from an economic point of view, the cost will be lower than that of the new bridge, and the cost can be effectively controlled.
