Analysis of crosswise vibration of pile driving

摘要

A rational mechanical model of foundation of precast concrete pile on layered elastic base when driving is established in this paper. Through dynamic analysis, the numeric solution of forced reaction of the foundation of single pile which eccentric dynamic vertical load acts on pile top is provided. And effects of excitation intensity, impact duration of pile hammer, diameter or length of side of pile, eccentricity of pile hammer, foundation modulus and coefficient of viscosity of soil to the dynamic response of pile are analyzed. The primary analytic method of studying the pile response which intense axial excitation and moment excitation act on, which is very important when studying the vibration of excited precast concrete pile.
