摘要: JA三维轴对称土模型出发,考虑桩周土体的三维波动效应,对均质滞回材料阻尼土中完整端承桩在垂直协和 激振力作用下的纵向振动特性进行分析,求解得到桩顶频域响应解析解、复剐度和速度导纳,利用卷积定理和傅里 叶逆变换,求得半正弦脉冲激振力作用下桩顶速度导纳时域响应半解析解

关键词: 波动效应, 频域响应, 复剐度, 速度导纳

Abstract: By using a soil modeling ofthree axes symmetry and considering three dimensions wave efect,the longitudinal vibration charaeterisitic is analyzed on condition that a vertical force being harmonious and stimulating force is loadoed upon the whole newel stake in the damping soil of homogeneous and detained materia1.The frequency domain response of the pile head,complex stifness and mobility can be obtained as wel1.According to the convolution theorem and the inverse Fourier transforms.a semi-analytic solution oftime domain response ofvelocity admittance is obtained on condition that a stimulating forces of a half sine pulsation.

Key words: wave efect, frequency domain response, complex sti~ness, mobility
