Abstract

Based on the plane strain model, a three-dimensional vibration model was setup for soil dynamic response of soil surrounding large diameter pile. An accurate analytical solution was got by considering the couple effect of vertical and horizontal displacement of soil. Through the discussion parameters slenderness ratio (L/d), hysteretic damping ratio (Ds,Dv) and soil Poisson's ratio (ν),it is concluded that they are very important for the vertical vibration propproperties of soil impedance.
