Abstract
In order to study the influence of fluid-solid coupling action when high temperature on distortion energy of asphalt pavement layer, choosing the typical asphalt pavement structure with semi-rigid base as the research object and using the finite element software of ABAQUS to create the three-dimensional finite element model of asphalt pavement with conditions of the fluid-solid coupling action at 60 ℃. To analyze the stress response of asphalt pavement layer below under the fluid-solid coupling action at 60 ℃, and then to analyze the influence on its distortion energy. The results show that: the asphalt pavement under the fluid-solid coupling action when high temperature, the vertical principal stress, shear stress and distortion of bottom of the asphalt pavement layer are higher than the asphalt pavement under the vehicle load action alone; Comparing to the vehicle load action alone, the distortion energy of the bottom of asphalt pavement layer under the fluid-solid coupling action when high temperature increased 1.89 times.关键词
