The Research of Steel Bracket Jacking Experiment in Long Span Continuous Beam Bridge
Bridge jacking technique in the old bridge reconstruction project have broad application prospect,this paper is aim to share the bridge jacking technique and design the steel bracket as the load carrying platform.The finite element calculation is conducted by ANSYS sofhvare considering the concrete material nonlinearity with reasonable stress-strain relationship of concrete and element type.Compared with the experimental data,the model reliabilities and the results of two test programs are evaluated.We can conclude that the second structure form of this paper is safer,which can provide the meaningful guidance for similar projects.
