Description:

Abstract:

In recent years considerable interest has been shown in the engineering properties of submarine sediments. To date, studies of these properties have primarily been based on procedures and techniques used in the field of soil mechanics for foundation investigations on land. This study was undertaken to investigate the feasibility of using these soil mechanics procedures in conjunction with submarine sediments. Bottom samples were collected from St. Andrew Bay, Florida and analyzed for the mass physical properties using standard soil mechanics procedures. The influence of sampling, using oceanographic techniques, on the engineering properties is considered. Predictions as to the penetration of various shaped cement blocks, based on standard bearing capacity formulae using the data derived from the laboratory tests, were made. These predictions were then compared with actual measurements made on the blocks after they were placed on the bay floor. The problem of core shortening and the accuracy of predictions based on these formulae are discussed.”

Purpose:

…A study was undertaken to determine the validity of applying standard soil mechanics techniques and principles to soft submarine sediments. The purpose of this investigation was as follows: To collect sediment cores from a bay, make the necessary engineering tests, calculate the sediment bearing capacity, predict the amount of sinking of various shaped concrete blocks into the sediment, observe the actual penetration of the blocks, and relate the observed penetration values to the predicted values. These data then would serve to indicate if a problem existed and, hopefully, what modifications might be applied to the present principles in order to more accurately determine the engineering properties of submarine sediments.”
