土—基础共同作用分析的有限元/无限元耦合方法模型研究
Finite/infinite element coupling method for analysis on the interaction of soil-foundation system
【摘要】 为考虑土—基础共同作用,建立了有限元/无限元耦合方法分析模型。通过对同一结构体系分别应用有限元理论和有限元/无限元耦合方法比较,研究了有限元/无限元耦合体系中有限元范围在水平与竖向区域的不同取值对计算结果的影响,从而确定了有限元区域的计算范围。结果表明,有限元/无限元耦合方法对于研究共同作用问题具有较高的精度和显著的经济性。
【Abstract】 To study the soil-foundation interaction,the model of finite/infinite element coupling method is set up in this paper.Through studying the same system,finite element method and finite/infinite element coupling method are used to analyze the influence on the(result) what is concluded by the different vertical field and horizontal field of finite element in the finite/infinite element system.The calculation range of finite element is determined,and it is shown by the calculation that the finite/infinite element coupling method has high accuracy and significant economy to study the interaction.
