Abstract:

Based on Biot’s consolidation equation,the characteristics of the resistance of soil caused by horizontal vibration of elastic bearing pile embedded in saturated soil are analytically studied. Transforming the consolidation equation, by virtue of differential operator splitting and variable separation method, the horizontal dynamical characteristics of soil under steady state of pile-soil interaction are obtained. The comparisons with the equivalent single-phase solution and the single-phase solution are presented; and the condition of the solution that can be equivalent to the equivalent single-phase solution is indicated. A parametric study is conducted to determine the main features of pile-soil interaction in horizontal vibration, the effects of the permeability coefficient, the pile-soil modulus ratio and the pile slenderness on resistance of soil layer are studied.

Key words: saturated soil, horizontal vibration, equivalent single-phase solution, impedance
