DYNAMIC RESPONSE OF PAVEMENT SUBJECTED TO MOVING LOAD

Cover Page

Abstract


The problem of dynamic equilibrium of the pavement under the action of moving load using ratios plane strain viscoelastic solid, resting on viscoelastic foundation is considered. By using finite difference method developed economical constitutive relation for numerical im- plementation of the problem. Approach to analysis in the frequency range is offered. Depend- ences of the road surface displacement amplitude on moving load speed for different values of foundation modulus are shown. Optimal speed of moving load is determined.
