| 摘 要： | 根据土体中抗滑桩的受力特性，利用Winkler模型和欧拉--伯努利理论，推导出了对抗滑桩的挠度表达式，并整理成“三次曲线”函数式．根据理论分析结合位于山东省泰安市境内的205国道高峪铺公铁立交桥边坡加固工程，利用计算机数值模拟技术，对稳定状态下抗滑桩整个桩体的轴向力和横向位移的变化情况进行了讨论，对桩体不同位置单元的抗滑力矩和承受的剪应力随时间的变化规律进行了模拟研究．

| Abstract: | According to the characteristics of anti-sliding piles setup in the soil slope, Winkler model and Euler-Bernoulli beam theory, the deflection expression of the piles was deduced and it was sorted out as a function of "Cubic parabolic". The axial force and deflection acting on the piles after the soil slope achieved stability, as well as the variability of anti-sliding moment and shear force on the piles in different elements with the number of computing steps, were analysed based on this function and the combinated of computer simulation (FLAC) with the practical engineering of GYP soil slope on No.205 national highway in Shandong province. |
