| 摘 要： | 结合桩岩作用的剪滑扩张规律，建立了适于弱质岩石嵌岩桩嵌岩段的荷载传递函数及相应的解析解。从理论上较好解释了桩端阻力随嵌岩比H/D的变化关系，分析了桩侧岩壁性质、桩端岩性等因素对单桩沉降与桩端阻力的影响，并提出了有关的设计建议。

| Abstract: | The characteristics of rock socketed pile is mainly decided by rock sockets. Based on shear expansion rule that is supposed to govern the pile-rock interaction, this paper uses load transfer theory to create a new load transfer function and generates a set of formulae suitable for soft rock socketed piles. Through analysis of these formulae and practical test results, it satisfactorily explained the relationship between pile-end resistance and socketed ratio H/D, investigated the effect of rock asperity and bottom quality, etc. on pile settlement and pile-end resistance, and also proposed some useful suggestions for socketed pile design. |
