摘要

Dynamic response of concrete pavements subjected to moving loads is analyzed by using the three-dimensional (3D) finite-element method in conjunction with Newmark integration scheme. The dynamic vehicle-pavement-foundation interaction effects are considered in the 3D finite-element algorithm. The moving vehicle loads are modeled as lumped masses each supported by a spring-dashpot suspension system and having a specified horizontal velocity and acceleration. Concrete pavements are considered to respond elastically and are represented by a series of brick elements. The present formulation considers a linear viscoelastic foundation model (Kelvin model) consisting of a system of discrete linear springs and dashpots. The interaction between concrete pavements and underlying soil foundation is considered. The present results are compared with the available theoretical results to validate the accuracy of the present algorithm. A study is conducted to evaluate the effects of various parameters on the dynamic response of concrete pavements subjected to moving loads.
