ABSTRACT

This study presents a mathematical solution to evaluate the response characteristics of a tapered pile embedded in cross-anisotropic medium, under lateral harmonic force. The resistance of the cross-anisotropic viscoelastic half-space to a harmonic force acting in the lateral direction is obtained. The soil is demarcated into an interior weakened and an exterior linear region. The proposed procedure is validated using a reported field test of forced vibration of a cylindrical pile. The present methodology is able to predict the resonant frequency within an error of 3.5–5.1%. Further, few parametric studies are conducted.

嵌入交叉各向异性介质中的锥形桩的横向动力响应

摘要

本研究提出了一种数学解决方案，用于评估嵌入交叉各向异性介质中的锥形桩在横向谐波力下的响应特性。获得了交叉各向异性粘弹性半空间对横向作用的谐波力的抵抗力。土壤被划分为内部弱化区域和外部线性区域。使用报告的圆柱形桩受迫振动现场试验验证了所提出的程序。本方法能够在 3.5-5.1% 的误差范围内预测谐振频率。此外，很少进行参数研究。
