摘要
本文考虑地面运动的影响和土的非线性性能下,提出了水平动荷下成层土中摩擦桩变形与内力的分析方法。还做了模型桩振动台试验。分析与试验结果表明,地面运动对摩擦桩下段动力反应的影响不可忽视。本文方法简单,实用,可供桩基抗震设计参考。
In this paper, an analytic method of deformation and interal force of fric-tion pile in layered soil under horizontal dynamic load is presented, consi-dering the effect of the ground motion and non-linearity, of the soil. In orderto simulate the horizontal ground motion, shaking table tests for frictionpiles were also made. The analytical and the experimental results show thatdynamic response of the lower section of friction piles to ground motion shouldnot be neglected. The proposed analytic method is simple and practical foruse in the seismic design of pile foundation.
