| 中文摘要: |
| 介绍了一种预应力混凝土异型桩，即预应力混凝土竹节桩。分别从外形、接桩方式、桩顶与承台的连接方式阐述了竹节桩与管桩的主要差异；并通过杭州地区抗拔工程中竹节桩与管桩的抗拔试验，对它们竖向抗拔极限承载力进行了对比研究。试验表明：竹节桩总体抗拔性能优于管桩，其竖向抗拔极限承载力相比管桩平均提高了约52%；且在相同荷载作用下，上拔位移不大于管桩；竹节桩在该区域抗拔工程中的应用，取得了良好的效果。 |
| 英文摘要: |
| This paper introduces a pre-stressed concrete special shaped pile which is called pre-stressed concrete bamboo-shape pile. The main differences between the pipe pile and pre-stressed concrete bamboo-shape pile has be expounded from the three aspects: shape, mode of pile extension and connection mode of bearing platform and pile. In addition, ultimate uplift bearing capacity of pipe pile and pre-stressed concrete bamboo-shape pile has been studied basing on the anti-pulling test which is conducted in Hangzhou. Comparing the ultimate uplift bearing capacity of two piles, the research shows that the anti-pulling behavior of bamboo-shape pile is better than that of pipe pile, and the ultimate uplift bearing capacity has been increased about fifty-two percent. Under the same load, uplifting displacement of bamboo-shape pile is less than that of pipe pile. The pre-stressed concrete bamboo-shape pile which is applied in anti-pulling project in Hangzhou has acquired a great of achievements. |
