【Abstract】 Dynamic response of structure is mainly dependent on the characteristics of load and structure. In this paper, the response of rigid pavement structure system under vehicle load was simplified as the dynamic response of 2-D plane with single freedom under the impulsive load. Based on the simplification, the analytical solution of dynamic response of pavement structure under vehicle load was derived, and the influence of the materials properties on the dynamic response of structural system was analyzed.更多还原
