Abstract

To study the quality disease and residual mechanical performance of bearings under the replacement of in-service bridges, this paper took the pot bearings under the replacement of a real bridge as an example to conduct appearance, mechanical perfornance, and raw material testing. Meanwhile, it determined the main causes of the disease led to by the replacement, analyzed the influence of bearing disease on the restrained concrete, and studied the performance improvement technology of in-service old bearings, with mechanical performance verification carried out. The results reveal that the main disease of pot bearings (replacement) is excessive wear of the sliding plates, which increases the friction coefficient of the bearings to 0.19 and changes the original constraint system of the bridge. Additionally, the process of employing steel hoops and new sliding plates can achieve rapid replacement of sliding plates of the bearings and shorten the interruption time of bridge traffic. Meanwhile, the rubber is in a closed environment, which can avoid the occurrence of aging rubber.
