| 摘 要： | 采用正弦-全塑性模型来描述嵌岩桩的侧摩阻力与桩土相对位移之间的传递关系,导出了无限长桩桩侧阻力与桩顶相对位移之间的解析解;同时桩端阻力与桩端位移之间采用负指数-全塑性模型描述,进而得出了桩顶沉降量与竖向承载力之间的关系。并通过对某一嵌岩桩静载试验数据进行对比分析表明,该计算方法与实测结果吻合良好,方法简单实用,具有一定...

| Abstract: | Adopting a sinusoid-fully plastic function,the relation between friction around pile and relative displacement of pile-soil has been described,the analytic calculation of infinite pile has been concluded between side friction force and displacement of pile top.Meanwhile,adopting a negative exponential function,the relation between tip resistance and end displacement has been described;the relationship between vertical bearing capacity and settlement of pile top has been put forward.The good agreement between calculated and experiment results of a rock-socketed pile has proved this calculation for some rock-socketed piles is practical and simple. |
