Obtaining Strength Profiles with Depth for Marine Soil Deposits Using Disturbed Samples


Three methods are presented for predicting the undrained shear strength of marine soils using parameters obtained from tests on disturbed samples. The predictions are developed from (a) a rational approach using critical state soil mechanics, (b) an empirical relationship with plasticity index, and (c) an association with the liquidity index. A series of case studies are reviewed leading to the conclusion that the rational critical state approach leads to a conservative estimate of peak strength for all cases except the underconsolidated soil; the empirical method provides a reasonable prediction of peak strength for normally consolidated soils; and the use of liquidity index provides a close estimate of remolded strength.
