Description

Technical Field

[0002] As an important infrastructure, the structural safety and durability of bridges are of great significance to transportation and socioeconomic development. In bridge structures, bearings are an important component connecting the superstructure and substructure of the bridge. The design and performance of bearings directly affect the service life and safety of the entire bridge. Traditional bridge bearing structures often face the following problems during long-term use:

[0003] 1. Load impact problem: Due to changes in vehicle loads, especially the passage of heavy vehicles, as well as wind loads, temperature changes and other factors, traditional bearing structures are prone to fatigue damage when bearing these dynamic loads, resulting in a decline in bearing performance.

[0004] 2. Temperature deformation: Bridge structural materials expand and contract with temperature fluctuations, causing expansion and contraction of the bridge structure. Traditional bearing structures are limited in their ability to adapt to these deformations, which can easily lead to stress concentration and affect the overall structural safety of the bridge.

[0005] 3. Earthquake effect problem: When an earthquake occurs, the bridge structure will be subjected to large horizontal and vertical dynamic forces. Under the action of the earthquake, the traditional support structure is prone to slippage, falling off or damage, seriously affecting the seismic performance of the bridge.
