The Prediction of Strength in the Sediments of St. Andrew Bay, Florida

C. W. Holmes, H. G. Goodell

ABSTRACT

The cohesion, or strength, of sediments from cores taken at ten sites in St. Andrew Bay, Florida, have been investigated as a function of a number of other sediment characteristics by multiple linear regression and nonlinear regression. Cohesion was measured by unconfined compression of vane shear tests. Strength in these sediments is found to decrease as sediment water content increases, to increase with depth in the core, and to increase with an increase in the ratio of kaolinite to illite. All of these variables are linearly related to strength. Water content, depth in core and the ratio of K/I are associated with a number of second order effects, most of which both increase and decrease strength. Penetration depends upon sediment water content, mean grain size, sorting, and void r tio.
