摘要
根据单桩-土系统横向非线性动力相互作用的简化分析模型,利用有限元空间离散技术和Newmark-β法,讨论 了横向动力荷载作用下,单桩的运动方程在时域中的求解方法.计算结果表明,该模型可以较好地模拟各种不同类型单 桩-土系统的横向非线性动力学响应.
In this paper, the finite element spatial discrete method and Newmark - β method are utilized to discuss the solutions of the motion equations for the nonlinear response of single pile under lateral dynamical loads in the time domain . The predictions of the model are in very good agreement with the measured values from experiments.
