摘要
鉴于嵌岩桩所处土层、岩层的性质差异，桩侧土层、岩层及桩端岩层采用不同的双折线荷载传递函数（ 弹性 全塑性模型、弹性 硬化模型） ，导出了嵌岩桩单桩沉降计算的一种解析算法．并利用所得公式对深长嵌岩桩沉降曲线特点，影响嵌岩桩单桩承载力、单桩沉降的因素等进行了讨论．讨论表明：桩身弹性模量 Ｅ、桩端岩石刚度 Ｃｂ 是影响桩端阻力发挥的重要因素，也是影响单桩承载力、单桩沉降的重要因素．
In view of the differences between soil layer properties and rock layer properties, with different bilinear load transferfunctions, a set of analytical equations for single pile settlement calculation of rock socketed piles are established. The socket length, the factors, influencing single pile bearing capacity and settlement of rock socketed piles and loading settlement curves are then discussed herein. The discussion indicates that the elastic module of pile and the stiffness of rock at the end of pile are the important factors, influencing single pile bearing capacity and settlement of rock socketed piles.
