by For a long time, bridge engineering in China has played an important role in road traffic in the economic market environment due to its advantages of carrying heavy loads, safety, and comfort.
With the rapid development of the national economy, in order to meet the demand for road transportation, it is necessary to pay attention to the quality of bridge construction.
As an important type of bridge, prestressed concrete bridges constructed in the early days may suffer from various structural damages due to different design standards, load types, and significant loss of prestress.
At the same time, due to insufficient load-bearing capacity and decreased durability of the beam body, it will have a serious impact on the safety of vehicle operation.
Based on this, under the new development situation, how to improve the bearing capacity of bridges and standardize construction technology has become an important guarantee to ensure smooth road operation.
