Study of slope instability in the ocean floor

Abstract

There are three sections to the report: (a) ocean floor soil types and characteristics; (b) stability analysis of submarine slopes; and (c) discussion of problems, w-ith conclusions and recommendations. in the first section the physical and mechanical properties of the soils encountered in various types of ocean-floor terrain are described and summarized in tables and diagrams. The application of conventional subacrial slope stability analyses to ocean-floor soils and their environment is examined in the second section. Some aspects of the stability of under consolidated soils forming in areas of rapid deposition are given particular attention. Following a summary of the conclusions reached in the study, some detailed recommendations regarding future studies and experimental work are given in the final section of the report.
