Liquefaction of Silts and Silt-Clay Mixtures

摘要: Low plasticity silts and silty clays occur extensively in the central United States. For evaluating their liquefaction potential during an earthquake, no guidelines are available based on density, void ratio, index, standard penetration values, or any other simple soil property. Their behavior is not properly understood at present often confused with that of sand-silt mixtures. Pore water pressures silt silt-clay mixtures discussed, influences index cyclic strength reviewed critically. It concluded considerable additional work needed to fully understand these soils.
