Saturation Effects on Soil Liquefaction
Liquefaction experiments are conducted with the Torsional Simple Shear Device on partially saturated loose Ottawa Sand with varying pore-pressure parameters ranging from 0.25 to over 0.9. A relationship between the pore pressure parameters value and the degree of soil saturation is established. It has been shown that even soils with low degrees of saturation do liquefy and that the pore-pressure buildup pattern in these soil samples is similar to that generated in fully saturated loose sands with densities less than 1.60 g/cc. Based on data acquired, the liquefaction potential for soils was found to decrease with decreasing degrees of saturation. In defining initial soil liquefaction potential, both the effective stress ratio and the effective stress path turnover point concepts yield the same results. A description of soil properties, the test device and test procedures followed during this investigation, the experimental data obtained, and a discussion and analysis of the data are given.
