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.
