Abstract
In this paper, the effects of the main property indexes on the saturation original loess liquefaction is analyzed through the dynamic triaxial test by using the WF-12440 testing system, combined with the experimental results, the influence of density-grain degree coupling on saturated loess liquefaction is comprehensively analyzed. The result shows that the influence of density-grain degree coupling on saturation loess liquefaction has a feature of segmentation, plastic index plays the main role for loose loess, whereas density is the main control factor to dense loess; Moreover, the influence of density-grain degree coupling on saturated loess liquefaction controlled by cyclic numbers of the vibration, plastic index plays the leading role while the vibration times is small, while the more vibration times, the bigger density and higher strength of liquefaction.
