| Abstract: | By using a soil modeling of three axes symmetry and considering three dimensions wave effect,the longitudinal vibration characterisitic is analyzed on condition that a vertical force being harmonious and stimulating force is loaded upon the whole newel stake in the damping soil of homogeneous and detained material.The frequency domain response of the pile head,complex stiffness and mobility can be obtained as well.According to the convolution theorem and the inverse Fourier transforms,a semi-analytic solution of time domain response of velocity admittance is obtained on condition that a stimulating forces of a half sine pulsation. |
