FREE BOUNDARY, FLUID FLOW, AND SEEPAGE FORCES IN EXCAVATIONS

This study developed a numerical model to investigate the influence of fluid flow on the strength and deformation behavior of unsupported and braced excavations. The details of the study are described, and the results are discussed. It is shown how increased effective stress near the stress-free surface (or near the wall, for braced excavations), leads to vertical consolidation. It is shown that the influence of fluid flow on the deformation behavior of excavations is significant, and is at least first-order, and should thus be incorporated into the analysis of critical structures whenever possible. These and other findings are discussed.
