A deep excavation in Berlin sand is a benchmark problem for the Cysoil and PH (plastic hardening) soil models in FLAC. The simulation follows the construction sequence: install diaphragm wall, dewater, excavate in four stages and install pre-tensioned anchors at each stage. The properties for the Cysoil and PH models are calibrated to provide a reasonable fit to field measurements for wall deflection.
