This research will investigate the contact problem between structures           and geologic materials subjected to static and cyclic loading.  A               continuum mechanics model will be developed which will include many             relevant phenomena such as state of stress and strain, hardening an             softening, fluid pressure in the geologic material, and deformation             modes.  Experimental techniques will be used to determine material              constants and to verify the model.  The result of this research can be          used in the design of structures founded on geologic materials                  subjected to earthquake loading.
