Abstract:In order to study the stress performance of integral bridge Z-shaped approach plate in Maluan Mountain of Shenzhen, the analysis model of Z-shaped approach plate is established by the finite element analysis software ABAQUS. The comparison is carried out with the experimental results. The influences of the different parameters on the stress performance of Z-shaped approach plate are studied and the influence of approach slab in pavement evenness is analyzed. The analysis results show that the working performances of the approach slab can be improved through the change of the inclined plate angle of Z-shaped approach plate. The change of pavement slope at the far end can satisfy the requirements of expressway pavement evenness when Z-shaped approach plate with arbitrary angles of inclined plate is pushed by the longitudinal bridge in one direction. The results of finite element analysis can provide some references for the design of integral bridge Z-shaped plate.
