Abstract

In this paper, the mechanism for soil liquefaction is tested in the field through observations and geotechnical analysis of soils that failed during a large storm in central California. Surprisingly, the AA. find that the debris flows mobilized from soils that were initially dense. In addition, they find that the potential for debris flow mobilization was strongly linked to the fines/sand ratio. The AA. present results from a numerical model. Because the rate of the approach to critical state is fundamentally a function of the hydraulic conductivity of the soil, sandy soils will approach critical state much more rapidly than clay-rich soils
