摘要：
Based on porous medium theory, the longitudinal coupled vibrations of saturated soil-pile is investigated with layer method by regarding soil around of the pile as saturated porous medium. A comparative analysis between the results of the three-dimensional model and Novak layer method is carried out; and validity of the results is shown. The influences of main mechanical parameters of pile and soil on dynamic behaviors of coupled system is analyzed; the results indicate that the length-diameter ratio and modulus ratio of pile and soil have a great effect on dynamic behaviors of the pile in saturated soil; while the influences of damping coefficient and coupling coefficient are smaller.
