✦ Synopsis

A two-dimensional axisymmetric model, formulated within the framework of a mixed finite element technique, is presented for analysing the interaction between a static axisymmetric load and a layered pavement structure. The model incorporates the closed-form solutions for the displacement and mean normal stress fields in the radial direction, thereby reducing the problem discretization to one dimension. Linear interpolation is adopted for displacements with constant mean normal stress within each element. The use of a mixed formulation allows one to obtain solutions to linear elastic problems in which the Poisson's ratio may equal one half. An example is presented which compared the model predictions with those obtained from a closed form solution.

After the application of a Laplace-Hankel transform, the governing equations of Biot's consolidation are solved analytically by using the eigenvalue approach. Then the analytical layer-element of a single soil layer can be obtained in the transformed domain by synthesizing the generalized displaceme
