In recent years, the rapid development of transport , bridges an important social infrastructure as China 's position has become more prominent, especially in highway bridges, urban viaduct has become a medium-sized city's main traffic arteries and hub in the national economy and people's daily life play an important role. Bridge bearings are an important part of the bridge structure , a direct impact on the life of the bridge and structural safety , where laminated rubber bearings because of its simple structure , reliable performance, easy installation and replacement , and low cost , is widely used in highway urban bridge construction. Firstly, the development and application of bridge bearings , use status and research trends were presented related to the introduction of the bridge seismic design methods and new design theory, discusses the bridge bearing the overall seismic performance of the bridge in an important role. And to bridge the current selection in the design of laminated rubber bearings , bearing manufacturing , site construction, sampling tests , maintenance management and other aspects of the weak links , combined with the Tianjin highway bridges, urban viaduct construction examples, references bearing design , assay method, construction technical regulations and other norms, illustrates the laminated rubber bearing design and construction of the control points , an analysis of its design selection , testing detection problem and propose a strategy to tackle common diseases on laminated rubber bearings made laminated rubber bearings treatment measures and routine maintenance methods , while for bridge maintenance , detailing the overall Lacquer continuous bridge replacement bearing construction method . Through the bridge laminated rubber bearing system study was to investigate several aspects , bearing in bridge structure to strengthen the important role of the construction proposed levels of design, construction , production and technical management personnel should fully understand the importance of quality support and strengthen quality management sense of responsibility , and constantly improve the level of bridge construction .
