.... Stresses and displacements at selected internal points in the medium can also be calculated from the known surface data. The performance of a Boundary Element program is assessed by comparison of the results of B.E. analysis of some simple problems involving non-homogeneous media, with results calculated...

... for the same problem calculated with the boundary element program, to demonstrate the validity of the solution procedure. Analysis of other excavation geometries, a d comparison with resui ts from independent three-dimensional analyses of these excavation shapes, indicate that the method of analysis...
