Study of Slope Instability in the Ocean Floor

摘要

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, with 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 subaerial slope stability analyses to ocean-floor soils and their environment is examined in the second section. Some aspects of the stability of underconsolidated 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. (Author)
