| 中文摘要: |
| 预应力高强混凝土管桩（PHC管桩）因其诸多优点被广泛应用，本文采用PHC管桩来加固某大型水闸软土地基，根据管桩长、直径和间距的不同提出了三种不同的布桩形式，分别建立了三维有限元模型且进行了计算，分析计算结果得出了一种最为合理的布桩形式，为该工程软土地基处理提供了一种可行的办法，也为其它存在类似情况的水工建筑物地基处理提供了一定的借鉴。文章末阐述了PHC管桩施工过程中的几点注意事项。 |
| 英文摘要: |
| The pre-stressed high strength concrete pile (PHC) is widely used because of its multiple advantages. In this paper, PHC tube pile was utilized to reinforce soft soils in a large water gate. Three different piles forms were proposed according to different pile length, diameter and spacing and three-dimensional finite element models were established respectively, the calculated results of which were then analyzed to give a most reasonable pile form. The outcome provides a feasible method for soft soil ground treatment in this project, it’s also of reference value for other similar situations. At the end of the paper several construction attentions of PHC tube pile were noticed. |
