ABSTRACT
Progressive failure can occur in slopes of strain softening material and is often recognized by large slide events triggered by a limited local disturbance. In Norway and Sweden such slope failures are often associated with soft, sensitive and quick clays. The mechanisms involved in progressive failure have been widely discussed (Bishop 1967, Bjerrum 1967, Bernander 2000, Andresen et al. 2002, Andresen & Jostad 2004, Gylland et al. 2010) and the reader is referred to these publications for further details.
