在八个calyey网站进行的43个驱动和静压桩荷载试验的结果进行了反分析，使用piezocone测试数据。本文提出了一种估算桩轴向承载力的方法，即由净修正锥阻力qnet计算桩的单位侧摩阻力和单位端阻力。利用该方法反算了压锥试验与单桩载荷试验之间的相关系数。由于大多数桩试验是拉力试验，因此特别强调了桩单元表面摩擦力的评估。关键词：粘土，桩，压锥，静力触探，桩轴向承载力，侧摩阻力。
Results of 43 load tests on driven and jacked piles performed at eight calyey sites have been back-analysed using piezocone test data. A method to evaluate the axial capacity of piles has been proposed in which the pile unit skin friction and the unit end bearing resistance are computed from the net corrected cone resistance, qnet. Correlation factors between piezocone and pile load tests were back-calculated using this approach. As most of the pile tests performed were tension tests, special emphasis was given to the evaluation of the pile unit skin friction. Key words: clay, pile, piezocone, cone penetration test, axial pile capacity, skin friction.
