| 摘 要： | 门架式水力插板桩是1种新型的空间挡土结构,其抗滑移稳定性计算目前尚无成熟方法.文中给出了直角坐标系下门架式水力插板桩抗滑移稳定性计算的简化Bishop积分方法和安全系数表达式,并编制了安全系数计算程序.通过1个算例,将此方法的计算结果与GEO-Slope有限元软件的计算结果进行了比较,表明了该方法是可行的.探讨了土体内摩擦角、粘聚力、桩入土深度和双排桩间距对结构稳定性的影响,得出了当土体的内摩擦角和粘聚力较小时,应通过增加桩的入土深度来提高门架式水力插板桩的抗滑移稳定性等一些有意义的结论.

| Abstract: | The portal water injection Sheet Pile is a new retaining structure, and presently there is no mature calculation method for the calculation of its stability against slide. In a conventional Cartesian coordinate system, a simplified Bishop integral method and the expression of the safety factor about the stability against slide are presented in this paper, and a program is presented for safety factor calculation. Through an example, the result based on the method in this paper is compared with that by Geo-Slope of the FEM software, and it is found the calculation method in the paper is feasible. Then, the influence of the internal friction angle of soil, the cohesion of soil, the embedded depth of the front piles and the space between the two piles on the structure stability is analyzed. Some beneficial conclusions are given; for example, when the internal friction angle of soil and the cohesion of soil are small, the stability of the structure can be improved by increasing the embedded depth. |
