Concrete canal linings with ferro-cement facings are analyzed in the form of isotropic elastic sandwich plates on Winkler type elastic foundation. Based on small deflection theory, a system of differential equations for the bending of the plate is developed by means of a variational theorem. The solutions of the governing differential equations are obtained in terms of Bessel and Hankel functions for the case of axisymmetric bending of a large sandwich plate subjected to a uniformly distributed circular load and a concentrated force. A simple but accurate technique of numerical integration is developed for evaluating the solution functions. The results from parametric studies are presented in the form of graphs for the purpose of analysis and design of such structures and a design example is presented.
