Creep behavior of fine-grained ocean sediments

Document Type


Date of Original Version



Long-term downslope creep deformations of submarine sediments have been studied through the use of geophysical evidence, laboratory testing and computational modeling. Results are presented of long-term, triaxial and direct simple shear creep tests of anisotropically consolidated specimens from the Gulf of Mexico. Axial, volumetric and shear creep strains were found to follow a simple logarithmic time relation. Some of the experimental data indicated that aging and history effects are present and that proper constitutive laws should contain this type of feature. -from Authors
