Wave-induced liquefaction of a saturated sand layer

Original Articles

The paper presents a theoretical study of the dynamic liquefaction of a saturated sand layer. The motion of the sand is induced by a periodic disturbance at the lower boundary of the layer, which simulates the influence of a plane excitation wave coming from below. The initial boundary value problem is solved numerically with the use of the hypoplastic constitutive equation for particular sand. Both horizontal and vertical disturbances are considered. The repeated deformation caused by a strong dynamic disturbance results in the reduction of the effective pressure and in the liquefaction of the sand. The degree of liquefaction as a function of the depth is nonuniform. The liquefaction patterns produced by vertical and horizontal disturbances are completely different.
