Document Type: Proceeding Paper

Part of: Sedimentation Consolidation Models—Predictions and Validation


Methods of predicting initial consolidation upon thawing and the subsequent consolidation with time under increasing pressures are presented in terms of changes in unit weight. Procedures for conducting one-dimensional consolidation tests on originally frozen specimens are described and analysis of laboratory tests with respect to total and differential settlement are discussed.
