| 摘 要： | 介绍了一种新型的抗拔（浮）桩——部分粘结预应力抗拔（浮）桩。该新型桩有效改善了抗拔桩的桩身结构,能充分发挥抗拔桩的承载力,改变了混凝土受拉时的受力性状,克服了普通抗拔桩容易产生裂缝的弊病。结合有关地下结构浮力方面的研究成果及现场实际的部分粘结预应力抗拔桩荷载试验结果,对抗拔（浮）桩进行了优化设计。

| Abstract: | The paper introduces a new uplift pile,part-bonding pre-stress uplift pile.It effectively improves the pile shaft structure;can make full use of the bearing capacity,remodel the mechanical characteristic of the stretched concrete and overcome the cracks of the normal uplift pile.Optimal design was made on the uplift pile by combining the research on underground structure buoyancy with the on-site test on part-bonding pre-stress. |

| Keywords: | part-bonding pre-stress uplift pile reduction coefficient of pore water |
