摘　　要：本文以“切石机基础-桩-地基体系的动刚度影响因素”为研究背景,首先在M Novak对桩基的研究基础上,从理论上分析了桩基的动刚度影响因素;然后选取某石材加工厂工程项目,运用ABAQUS软件对切石机基础-桩-地基体系进行了有限元建模;最后进行动力仿真分析,分别从有无桩、桩端土、桩身混凝土强度、桩土摩擦系数等情况,对影响结构动刚度的因素进行了分析,其研究成果对工程的设计、加固、减振提供了指导。Based on the research background of"affecting factors of dynamic stiffness for stone cutting machine-foundation-pile-foundation system",firstly,this paper analyzes affecting factors of the dynamic stiffness for pile foundation theoretically on the basis of M Novak's research on pile foundation;secondly,the finite element modeling and dynamic simulation analysis of the stone cutting machine-foundation-pile-foundation system are carried out by using ABAQUS software in a engineering case;finally,the factors affecting the dynamic stiffness of the structure are analyzed from the aspects of whether there is pile,soil at the end of the pile,concrete strength of the pile,friction coefficient of the pile and soil,etc.The research results provide certain guidance for the practical application of the project.
