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 in the nature of the soil and rock layers in which the rock-socketed piles are located, different bifurcation line load transfer functions (elastic full-plasticity model, elastic hardening model) are used for the soil layers, rock layers, and end-piles of the piles, and rock piles with rock-socketed piles are derived. An analytical algorithm for settlement calculation. And use the obtained formula to discuss the characteristics of the long-term rock-socketed pile settlement curve, the bearing capacity of the rock-socketed pile, the factors of single pile settlement, etc. are discussed. The discussion shows that the elastic modulus E of the pile body and the rock stiffness Cb at the end of the pile are important factors influencing the resistance of the pile tip, and are also important factors affecting the bearing capacity of the single pile and settlement of the single pile.
