Abstract
Using a newly developed large ring-shear apparatus, a series of tests was conducted on silty soils to study their undrained shear behavior. The samples were made by mixing loess into a fine-grained silica sand with 10, 20, and 30% loess by weight. By performing tests at different initial void ratio, the undrained shear behavior of samples with different loess contents at loose and medium-dense states was presented and discussed. Basing on the tests results, effects of loess contents on the peak and residual shear strengths are examined. It was found that adding loess into the host sand could lower the peak and residual shear strengths; and these two strengths decreases with increasing loess content. Meanwhile, with increasing loess content, the dissipation of generated pore pressure from the shear zone becomes remarked slower when the shear box was turned into drained conditions, and there is little, if any, dissipation for tests on the mixture with 30% loess.
