Abstract

In this paper, a simplified approach based on spline semi-analytical method is proposed for dynamic response analysis of visco-elastic layered half-space foundation. For varied geometrical and physical properties, the compliance function of layered non-homogeneous foundation is studied. Then an efficient and reliable numerical procedure for back-calculating material properties of pavement through the data measured from in-situ Falling Weight Deflectometer (FWD) tests is presented. The simulation results for in-situ data show that the proposed methodology is workable and applicable.

A Simplified Method of Vibration Analysis of Layered Foundation and Applications in Pavement Parameter Identification

San Diego, California

In this paper, a simplified approach based on spline semi-analytical method is proposed for dynamic response analysis of visco-elastic layered half-space foundation. For varied geometrical and physical properties, the compliance function of layered non-homogeneous foundation is studied. Then an efficient and reliable numerical procedure for back-calculating material properties of pavement through the data measured from in-situ Falling Weight Deflectometer (FWD) tests is presented.
