Rapid Disposal Of Laminated Rubber Bearing Bridge Technology Research

As China's economic development in recent years, as a hub of traffic arteries and bridges inthe country the status of social infrastructure significantly improved, particularly in urbanviaduct and highway bridges in the national economy and the daily life of residents is animportant role to play. Bridge bearings as an integral part of the bridge, directly affecting thestructural safety and life of the bridge length,the laminated rubber bearing due to its simplestructure, reliable performance, easy installation of replacement, low cost, it is widely used inhighway, bridge construction in the city.In this paper, laminated rubber bearing China in recent years in the course of the emergenceof some diseases and problems, first use of the state bearing the investigation and research, anddisease in the laminated rubber bearing and the bearing causes damage to the basis of themechanism , proposed a laminated rubber bearing disease prevention and control measures;through the cracks of bearings, bearing crack observation instrument was developed through thecrack observation instrument bearing the lateral surface of the protective layer of rubber bearingsfor quick determination of the thickness.Paper in the analysis of computer simulation based on the work of the interior state oflaminated rubber bearing modulus load test and the test based on the analysis of aging andfatigue before and after the performance before and after the change of bearing, made oflaminated rubber bearings repair method, obtained on damage to the bearings quick disposalmethods. Thus corrupted for the bridge after the laminated rubber bearing for possible quick fix,to ensure the normal operation of bridge safety.
