Details and Description: 

The simulation of a test wall construction in well-graded sand is performed with FLAC.  The construction steps include eight excavation stages with shotcrete, tiebacks and soil nails emplaced as support at each stage.  The tiebacks are pretensioned to a specific lockoff load. Development of forces in the support and soil deformation are monitored throughout the construction process.
