| 摘 要： | 本文基于桩的荷载传递概念,提出了计算单桩负摩阻力的力学模型,该模型不仅适用于端承桩,也适用于端承-摩擦桩或摩擦桩,同时该模型也便于考虑多层土中桩的负摩阻力的性状。两个实例的计算结果表明,本文提出的模型比较符合实测结果。

| Abstract: | Based on load transferring concept, this paper presents new method of analyzing negative friction of piles. This method is not only suitable for an end-bearing pile but also for a friction pile. Some comparisons are made between measured and predicted distribution of down drag forces of piles in layered strata. The results show that the agreement between theory and observation is satisfactory. |
