Swelling rocks are relatively soft rocks that swell when given access           to water.  The resulting movements cause problems in tunnels and open           excavations, in slope stability problems, and with shallow                      foundations for buildings.  The techniques that have been used to               estimate movements have been found to be quite inaccurate and, as a             result, designs are usually empirical, with numerous resulting                  problems.                                                                       This proposal involves a preliminary effort to develop experimental             techniques to be used in developing general three-dimensional                   constitutive models to describe the swelling behavior of these rocks.           Subsequent research will involve application of the apparatus with              actual swelling rocks and, hopefully, full scale field case                     histories.
