Abstract

In order to study the numerical law of dynamic deflection response of typical pavement structure under different impact loads

the grade highway information is experimentally surveyed

the measured data is analyzed

the correlation between grade highway bearing capacity and pavement structure is summarized

and the typical pavement structure under the dimension of bearing capacity is constructed based on the statistical law. And then a multi-layer continuous road structure model including plastic damage is established. The effectiveness of the model is verified by comparing the simulation results with the experimental data

and the influence of the size of the model on the simulation results of pavement deflection under different impact loads is studied. Finally

the deflection response law of typical pavement structure under different impact loads is studied

the peak settlement and residual settlement of pavement under impact load are calculated

and the internal law of deflection response of typical pavement structure under different impact loads is revealed. The result shows that the multi-layer continuous road structure model including plastic damage can accurately reflect the real dynamic deflection response of pavement under impact load; under different impact loads

the proportion of plastic settlement in pavement settlement and the amplitude of impact load meet the double exponential equation; in the range of 100 tons

the elastic rebound part of pavement settlement increases with the increase of impact load amplitude

and the plastic settlement part has an exponential positive correlation with load amplitude; the elastic rebound in pavement settlement reaches the upper limit of 1.2-1.3mm above 100 tons

the plastic settlement of pavement has a linear relationship with the load amplitude. In addition

the research on the influence of model size on simulation results under different impact loads can provide a reference for determining the appropriate size of simulation model in finite element simulation.
