    Abstract

    This paper describes triaxial testing procedures and corresponding methods of interpretation to find relevant effective stress-based soil parameters as input to stability analyses of marine structures. The main emphasis is laid on interpretation of static and cyclic triaxial test results with respect to shear strength parameters and pore-pressure characteristics. Examples of tests on marine soils are presented, and resulting design profiles are applied to investigate the foundation stability of a gravity platform during a 100-year design storm.
