Two current methods used in China for the computation of embedded pile are briefly analysed in this paper. There are a variety of opinions on the use of "Foundation Reaction Coefficient Method" based on elastic theory for solving the resisting force of piles in sliding mass directly,and meanwhile, an elastoplastic composite solution with boundary condition of ultimate equilibrium state of stress in the soil mass overlying the sliding plane,i.e.the"Equivalent Foundation Coefficient Method" is proposed.In addition, it is tried, in this paper, to find out the design load acting on the piles by analysing the interaction between piles and the sliding mass and to demonstrate the force transmission behavior of the soil mass between piles and thus to solve the problem of determining the spacing of piles.However, as indicated in this paper, the load condition of pile is rather complex, especially the interaction between the pile and the sliding mass can hardly be got clear, so far the above-mentioned idea is erely an attempt in theoretical work and needs to be verified by experiments.

本文简要分析了目前国內计算埋式抗滑桩的两类方法。对于以弹性理论为基础的“地基反力系数法”直接用于求解滑坡体內桩身的抗力这一问题有不同看法。同时提出以滑动面上土体所具有的极限平衡应力状态为边界条件的弹塑性混合解法,即“换算地基系数法”。本文还试图从分析桩与滑体相互间的作用,来寻求作用于桩上的设计荷载,阐明桩间土体的传力性能,以及解决桩间距的计算等问题。然而,正如文中所指,由于抗滑桩的受力情况甚为复杂,尤其是桩与滑体相互间的作用难以简单地弄清楚。因此,上述一些设想仅仅是从理论上进行分析的一个尝试,向有待于实践验证。

Basing on the elastic theory in this paper the formulas to calculate the internal force of two-span and tri-span continuous plate bridges under wheel load are derived respectively, and the concrete calculation according to the current national design load standard with two-width bridge is made. This calculation indicated that some specifice-tims in the current norm[1] are still applicable for continuous plate bridge. They are simple and convenient, if only the correction factor is taken into account.
