Analysis of Submarine Flow Slides in Fine Silty Sand
The mechanism of instability in granular soils is briefly explained, and its requirement as a forerunner for liquefaction of level or sloping ground is described. Tests on loose silty sand indicate a `reverse' behavior with respect to confining pressure and as opposed to the behavior of loose, clean sands. Strong correlations between fines content, compressibility and liquefaction potential are found for these soils. A procedure for analysis and evaluation of static liquefaction of slopes of fine sand and silt such as submarine slopes is presented. It involves determination of the region of instability in stress space in which potential liquefaction may be initiated and determination of the state of stress in the slope. The instability line and the region in which potential liquefaction may be initiated can be determined from consolidatedundrained triaxial compression tests, and a method of finding the state of stress is developed to predict the zone of potential liquefaction in simple slopes.
