Abstract:
The jointless bridge cancels the expansion device(expansion joint), fundamentally eliminates the diseases and maintenance replacement problems caused by the expansion device, and has good economic and social effects. Investigation and analysis were carried out on the construction trend, application type, regional distribution, bridge length, upper and lower structures, and approach slab of jointless bridges in China. The results show that China has built 70 jointless bridges by the end of March 2022. Jointless bridge is widely used in developed countries, but it is still in the start stage in China. The number of jointless bridge in China is increasing, the growth rate has accelerated since 2010, and the application proportion of the integral abutment bridge has increased. Jointless bridges have been built in more provinces, and new applications can be found in severe cold area. Existing jointless bridges are mainly small and medium span bridges with a short total length, and most of the jointless bridges are multi-span bridges. The superstructure is mainly concrete hollow slab. For the substructure, spill-through abutment with column stub is widely used in various jointless bridges. The thin-walled light type abutment is mainly used in integral abutment bridges. The gravity abutment is mainly used in semi-integral abutment bridges and deck-extension jointless bridges. The concrete pile-extension pier is mainly chosen as the piers. Grade flat approach slab is the most used type of approach slab. In the future, it is suggested to increase the number and application regions of jointless bridges, strengthen the promotion of integral abutment bridges and the research and application of jointless retrofitting, expand the application scope of the span, total length, curvature radius and skew angle of jointless bridges, and promote the development of jointless bridge technology in China.
