ENGINEERING PROPERTIES OF MARINE SEDIMENTS.

Abstract

Ocean-bottom sediments are considered from the point of view of emplacing or mooring structures. Bottom topography and sediment distribution around the North American continent are surveyed in detail. Soil mechanics concepts such as shear strength, compressibility, permeability, porosity and void ratio are introduced and used as a framework for discussing the sparse quantitative information concerning the engineering properties of bottom sediments. The low bearing capacities (often less than 1/2 p.s.i.) and high compressibilities of the sediments are seen to be particularly striking when compared with dry land values. The implications of these numerical data for ocean-bottom engineering are considered, and two programs, one minimal, the other ideal, for future sediment investigations are recommended. (Author)
