Abstract: The most accurate method for determining the bearing behavior of a pile is the stress test method，but the cost is high and it is difficult to be popularized in practice.According to the transfer line during the axial force of pile and transitional model load were deduced by using the representation of the compression of pile side resistance and tip resistance ratio formula，by introducing the concept of characteristic，established the settlement and bearing(Q-S)theory and method of character parameter analysis of pile by characteristic line coordinates，which has been proved feasible.

Key words: pile, characteristic line, bearing character

摘要： 确定桩的承载性状最准确的做法为应力测试法,但造价较高,难以在实践中推广应用。根据荷载传递过程中桩身轴力的界限型和过渡型模型,推导出了用桩身压缩量表示的侧阻和端阻占比表达式,通过引入特征线的概念,建立了在荷载和沉降(Q～S)坐标下用特征线参量分析桩承载性状的理论和方法,经实践验证是可行的。
