| Abstract: | In this paper, it were systematically studied by series of tests that the liquefaction mechanism of the remolding silt with different gradations and clay mineral components, variant clay particle contents and dry unit weight. One of the laboratory tests was run on remolded silt by using cyclic dynamic triaxial device, the other was carried on Scan Electronic Microscope (SEM). The results drawn why the lowest dynamic shear strength is at 9% of clay particle contents, which is found here and under various regulations of cyclic stress. |
