In the Northern part of the United States, a variety of structures              (small buildings, highway embankments, tanks) are supported at                  shallow depths on soil deposits composed of a crust (1 to 5 meters              thick) overlying a deep layer of soft clay.  It is often uneconomical           to provide support for the structures using deep foundations which              penetrate through the soft clay to harder layers underneath.  For               shallow support, the ability to perform analyses that include the               effects of the stiff crust are important.  Unfortunately, the                   physical properties of the crust are difficult to measure and                   analyses for a layered system (soil layers of varying properties) is            difficult.                                                                      This proposal provides for a careful set of physical measurements of            the stress-strain properties of hand carved samples of a desiccated             crust in Maine, and for analytical work needed to allow these                   properties to be modeled properly in theoretical analyses.  The                 results of the study should make foundation design more economical              and minimise the probabilities of failures.
