Abstract:
For the requirement of engineering practice, a new method for analyzing rigid pavement on the multiple layered foundation is presented in this paper. Based on the elastic thin plate theory and the theory of multiple layered elastic system, as well as the Hankel integral transformation, the formulas for calculating stresses, strains and displacements in the plate and the layered foundation under an axisymm-etrical circular uniform vertical load are developed in this paper. This method has been programmed for DPS-8 computer in the computing center, Nanjing Institute of Technology. The method presented in this paper can be used to design rigid pavement with n layered foundation in highway and airport engineering, as well as to analyze the operating conditions of the foundation under the rigid pavement, and hence to investigate the design method of the layered fonudation under the rigid pavement.
