- 論文の詳細を見る
The key findings in the previous studies on the deformation of sand are first reviewed to the necessary extent. Then, in summary form, five fundamental postulates are introduced as the bases on which a model of undrained deformation of sand under cyclic loading is to be established. The procedures for assessing pore pressured, shear strains and consequent occurrence of liquefaction during cyclic loading are illustrated on the diagrams based on the above postulates as well as actual data obtained in the static triaxial tests. The undrained performance of sand predicted by the proposed model were compared with several cyclic triaxial test results conducted under various conditions. These include stress and strain controlled tests; static and dynamic tests; and the tests cycles with constant and erratically changing stress amplitude. The comparison disclosed the relevance and applicability of this method of approach.
