摘要
This paper examines the mechanical response of precast panel pavement repair joints under static aircraft loadings using the finite-element method. Three-dimensional finite-element models were developed using the Abaqus software code, and their results were compared to and validated against results of full-scale field tests and theoretical calculations. Unlike previous pavement repair modelling efforts for precast panels and dowel retrofitting studies, all parts of the repair joint were modelled, including the dowels, dowel slot material, parent concrete, precast panel and pavement sublayers. Results show that high stress concentrations occur in the dowel slot material and that the current panel design is likely to be improved by modifying the dowel diameter.
