A study on small strain shear modulus of undisturbed soft marine clays and its correlations with other soil parameters

摘要

A study on small strain shear modulus (G_0) of naturally deposited fine grained soft marine soils on five soil deposits, namely, Ariake and Hachirogata of Japan, Pusan of Korea, Bangkok of Thailand and Bothkennar of UK, has been done using field seismic cone tests and also laboratory bender element tests at insitu stress states as well as isotropically normally consolidated stress states. Based on these and other data obtained from several other sites, general characteristics of G_0 and its correlations with other soil parameters have been examined. Finally, relation of the G_0 with soil parameters measured by the field vane, piezocone and dilatometer tests have been investigated using high quality insitu data acquired from twelve different fine grained soils deposits from various parts of the earth.
