Key Technology Study for Widened Continuous Hollowcore Slab Bridge

Abstract:

The key technology for widen continuous hollowcore slab bridge with long unit is improved. Taking Taiping flyover in Guangshen highway as an engineering background, the principles of splice joint are given, extension schemes are analyzed and compared in this paper. A reasonable scheme is decided finally and a 3D finite element model is established to check if the structure is satisfied with the requirement form the codes. After the extension project is finished, a local monitoring is carried out, including monitoring for stress and settlement. Both the calculated result and the test result are in acceptable range and satisfied with current codes. The research shows, the rigid joint structure adapted in this paper is reasonable.
