摘　　要：采用线弹性-塑性荷载传递函数，导出了成层地基中桩的轴向荷载-沉降曲线的解析递推公式。通过拟会实测Q-S曲线，可得到桩上系统的工程力学参数，并由此计算得到桩身轴力及侧摩阻力分布曲线。经许多工程验证，该方法有广泛的适用性及较高的分析精度，对分析桩的荷载传递机理、指导桩的工程设计及工程测试具有实用价值。With linear elastic-plastic load transfer function, a set of analytical equations for the axial load-selilement curves of pile were established, and a simplilied recurrence procedure was proposed to analyze the load-setilement behavior of pile in layered soil. This paper will be of practical significance for design of pile foundation. Several case studies are given to show the effechveness of this method.
