In the construction process of leveling steel plates for bridge supports, the placement method needs to be flexibly selected according to the longitudinal and transverse slope design and construction conditions of the bridge. The core goal is to ensure that the bottom of the beam is in horizontal contact with the top surface of the support without gaps, in order to achieve uniform stress on the support.
The bridge bearings are developed based on the specifications of JT/T4-2019, JT/T663-2019, JT/T391-2009, GB/T17955-2009, and JTG D62-2019 for the design of reinforced concrete and prestressed concrete bridges and culverts for highway bridges, using dynamic analysis.
In the field of bridge engineering, the selection of bridge bearings is crucial, as it is like the "joints" of a bridge, directly affecting the stability, durability, and safety of the bridge structure. However, in practical engineering, there are many misconceptions about the selection of plate, bowl, and ball bearings, especially in the judgment of load limits and applicable scenario boundaries. A slight mistake may pose a safety hazard to the bridge. Next, we will delve into the misconceptions that these three types of supports are prone to in these areas.

During the use of bridges or building structures, bearings may need to be replaced due to aging, deformation, or design adjustments. One of the key steps in replacing bearings is lifting construction, which involves using external force to partially lift the structure and create operational space for bearing replacement. This process requires rigorous technical solutions and standardized operations, which will be explained from multiple aspects below.
