Abstract

Abstract

In order to study the mechanical response characteristics of GFRP reinforced sea sand concrete pavement under vehicle loads, GFRP reinforced sea sand concrete pavement is applied to engineering practice. In this study, a 17 m×98 m GFRP reinforced sea sand concrete pavement was poured in the field vehicle test, and the field test showed that the change of rebar type and single-layer reinforcement ratio had little effect on the strain of the road panel under vehicle loads. At the same time, based on the field test data, the finite element model of the GFRP reinforced sea sand concrete pavement was established for parameter sensitivity analysis, and the results showed that the calculation results of the finite element model were close to the experimental data, and the model had high reliability, and the changes of the elastic modulus of GFRP panel rebars, the spacing of GFRP longitudinal rebars, the diameter of dowel bars and the elastic modulus of dowel bars had little effect on the maximum tensile stress of the GFRP reinforced sea sand concrete panel, and the load transfer performance of GFRP dowel bars was weaker than that of reforcing steel dowel bars. In actual engineering, the load transfer capacity of transverse joints can be improved by increasing the diameter of GFRP dowel bars.
