由P-S曲线确定摩擦桩单桩的有效桩长

摘要

在分析摩擦桩的刚度与桩长之间关系的基础上，根据正常工作荷载下，桩与土处于弹性状态的假定，提出了一种计算有效桩长的方法，并结合现场实测的数据证明了此方法的可靠性，此方法对于研究摩擦桩的刚度问题有一定的实用价值。%Based on the relation of stiffness and valid length of pile, assumed pile and soil in the elastic state under normal working load, the method of calculating the valid length of pile is given and the reliability of the method is proved by the example. The method is useful for studying the stiffness of friction pile.
