沥青路面流固耦合作用对面层畸变能的影响
Influence of asphalt pavement under fluid-solid coupling on surface distortion energy
摘要
Abstract
In order to study the effect of asphalt pavement of fluid-solid coupling on the surface distortion energy, the typical asphalt pavement structure with semi-rigid base was chosed as the research object. The three- dimensional finite element model of full-water asphalt pavement was established by virtue of the ABAQUS finite element software. The maximum principal stress and shear stress response at the bottom of each asphalt layer was analyzed on the basis of the porous medium of fluid-solid coupling theory. And the surface distortion energy was then analyzed. The research results show that the asphalt pavement under the action of water-coupling dynamic load, the bottom of the layers below, which the maximum principal stress and shear stress, fluctuated change, surface distortion can also show volatility change, and distortion energy from above to below layer gradually decreases, and the distortion can vary between adjacent layers is larger, the above layer under the maximum distortion energy is 9.86 times as much.关键词
