| 摘 要： | 遮帘桩作为挡土桩在深水建港、深基坑开挖及护岸工程中应用越来越广泛.为了研究开挖过程中遮帘桩的工作性状,运用大型有限元软件建立三维有限元的遮帘桩结构模型,模拟某板桩码头港池开挖.分析港池开挖后遮帘桩的刚度、桩长、桩间距及遮帘桩与板桩墙距等对板桩墙结构的影响,从而提出控制板桩墙结构变形、保持港池开挖后稳定的遮帘桩布置方法.研究结果表明,增加遮帘桩桩长和刚度能有效减小板桩墙的变形、陆侧主动土压力和弯矩,而遮帘桩间距和墙桩距的变化对遮帘桩挡土效果的影响不明显.

| Abstract: | Covered pile has been widely used as a kind of retaining pile in some projects,such as like deep-water port projects,excavating projects for foundation ditches,and retaining wall projects.The FEM software ANSYS is employed for the analysis of the 3D finite covered pile model in the paper,and the excavating process of a sheet pile wharf is simulated.The factors such as rigidity,length,space of covered piles,and space between the covered pile and sheet-piled wall are detailed in the paper,which influence the ... |
