| 摘 要： | 针对嵌岩桩荷载传递研究中存在的问题,根据桩体与围岩体接触面上的应力-应变关系以及剪滞模型,研究了嵌岩桩的荷载传递特性。推导了考虑桩、岩界面脱黏与完全黏结两种条件下嵌岩段侧阻力分布规律的计算公式。研究了桩、岩相对刚度、外荷载等级对荷载传递特性的影响,讨论了桩端荷载分担比例与嵌岩段所需埋设深度的关系等。研究成果对嵌岩桩设计具有指导意义。

| Abstract: | A model has been developed for shear distribution at the pile/ rock interface in a single rock-socketed pile subjected to vertical loading.Which accounts for the interfacial bond condition and is based on a shear-lag analysis.The new closed form solution has been established for a single rock-socketed pile under vertical loading.And to investigate the influence of relative rigid of pile/rock and loading grade on load-transfer of rock-socketed pile is discussed. |

| Keywords: | rock-socketed pile oad transfer shear lag model |
