摘要: Based on the fictitious soil pile model, effect of sediment vertical dynamic impedance rock-socketed with large diameter was theoretically studied by means Laplace transform technique and function transfer method. Firstly, under assumed to be same sectional area. The Rayleigh-Love rode model used simulate consideration lateral inertial large-diameter pile. layered surrounding soils bedrock were modeled plane strain model. Then, virtue initial conditions boundary soil-pile system, analytical solution at head derived for arbitrary excitation acting head. Lastly, based presented solution, properties, property investigated in detail. It is shown that properties have significant ability system resist deformation weakened increase thickness, but amplified shear wave velocity sediment. improving, vibration improvement property.
