摘要
本文将工程中常用的密集打桩土体模拟为正交各向异性弹性体。建立了刚性基础-桩-土这一空间相互作用系统的模型。根据圆柱体柱坐标的极点条件。分别选取了两组位移函数来表征桩基和土的位移,并用子区间法分析了结构-桩-土系统的相互作用地震反应。
In this paper,the soil-pile system is simulated as unisotropic elastic solid,the mechanical model of thefoundation-pile-soil interaction system is presented.According to the condition at the origin(r=0),twoadequate displacement functions are selected.The subinterval method is adopted in the calculation of struc-ture-pile-soil earthquake responses.
