摘要
以弹簧模拟桩-土的相互作用,建立了桩-土结构的有限元模型。结合工程实例,采用该模型计算了桩基的自振频率,分析了弹簧等效刚度的变化对模型自振频率的影响。
The paper analyzed the calculation of natural frequency through building a finite element model considering pile-soil interaction,which was simulated by springs.Meanwhile,the natural frequency was calculated using this method in an example,and the natural frequency affected by the change of equivalent spring stiffness was also analyzed.
