| 摘 要： | 研究门架式水力插板桩的抗倾覆稳定性,以确定其入土深度和工程安全以及工程造价。通过对目前较常用双排桩的稳定性计算分析,提出了1种新的桩土整体抗倾覆稳定计算模型,即将双排桩和桩间土视为1个整体,考虑双排桩桩间土的剪切破坏面随双排桩入土深度的变化,给出了门架式水力插板桩抗倾覆稳定性计算方法。并通过1个实例计算,验证了本文计算方法的可行性和一些有意义的结论。

| Abstract: | The stability against overturning of portal water injection sheet piles is the main factor for determining the embedded depth,the construction cost and the overall stability and safety of the portal structure.However,there is no perfect method for its calculation at present.Through an analysis and calculation of the stability against overturning of presently commonly used double-row piles,a new calculation model of stability against overturning is put forward,and the calculation method for stability against overturning of portal water injection sheet piles is presented.The calculation model regards the portal structure and the soil between the double-row piles as an entirety,and considers the variation of the shear failure plane of the soil between the double-row piles with the embedded depth of the piles.Finally,through an example,the method is proved to be feasible,and some beneficial conclusions are obtained. |
