• The finite element method has been used increasingly in recent years to simulate the process of excavation. When the soil is linearly elastic, the results of excavation must be independent of the number of steps in the cutting process. However, recent experiences with finite element analyses indicate that the results of actual computer runs can be seriously in error and, in particular, the displacements at the top of a vertical cut can appear to depend on the number of steps of cutting into an elastic soil. It is shown that these errors are caused largely by the inability of the finite elements to model adequately the stress gradients near the toe of the excavation. A modified procedure is recommended, and it is emphasized that such simulations of excavation should be done in as few steps as possible.
