Abstract: The development and components of a geotechnical analysis system are described and illustrated for drilled shaft foundations. This finite element-based analysis system incorporates several nonlinear material models of increasing sophistication. Both excavation and construction are modeled to simulate shaft construction. Nonlinear and cross-anisotropic variations in the in-situ stresses can be specified. The system verification is discussed and its use demonstrated with belled shafts.
