Rubber bearings of highway Bridges, as the link between the superstructure and the substructure, undertake the key functions of load transmission and deformation adaptation. Their working condition directly affects the safety and durability of the bridge structure. This article, through on-site detection and analysis, explores the common types of damage to bridge rubber bearings, their causes, and maintenance plans, including local treatment and bearing replacement, and verifies the application effect of the technology with engineering examples. The research results show that the damage of rubber bearings is related to multiple factors such as material aging, overload, installation deviation, and environmental erosion. Scientific selection of maintenance techniques and strict control of construction quality can effectively restore the function of the bearings, extend the service life of the bridge, and provide technical references for bridge maintenance projects.
