摘要

The disturbance of a clay mass due to the installation of a driven pile is modelled as an undrained, cylindrical cavity expansion under conditions of plane strain. Using a numerical solution technique predictions are made of the stress changes and the excess pore pressure distribution at the end of cavity expansion and of the subsequent stress changes that occur as the clay reconsolidates around the pile. Several constitutive models have been adopted in an attempt to idealize the clay behavior. In particular, solutions are pursued in depth for a work-hardening elasto-plastic model (modified Cam-Clay).
