Application of boundary element method to identifying the boundary conditions of pavement ‐ subgrade system

Abstract In this paper, the pavement‐subgrade system is modeled by a lot of rectangular thin plates on an elastic foundation, and the various joint restraints between these connected plates are simulated by generalized boundary conditions with a number of undetermined parameters. A boundary element method is developed for the free vibration problem of plates resting on an elastic foundation. The identification procedure is performed by combining the boundary element method with optimization techniques. Two examples, respectively associated with plate structures and the pavement‐subgrade system, are presented to illustrate both the boundary element method and the identification procedure proposed in this paper.
