对现阶段抗滑桩设计中几个问题的再讨论

现阶段抗滑桩的设计方法主要还是参照桥梁桩基的设计方法推导、发展、演变而来；通过对目前滑坡防治工程中抗滑桩设计的步骤、设计理论和方法加以总结和分析，指出了现今抗滑桩设计理论中仍存在的一些问题，特别是作用于桩身荷载的不确定性以及荷载分布形式的不确定性是现阶段抗滑桩设计中亟待解决的问题，并且提出应以被动桩的观点来进行抗滑桩的设计。对于所有这些问题的解决将会使抗滑桩设计的理论和方法更加趋于完善和合理。

Further Discussion on Some Questions in Designing Anti-sliding Piles at Present

Nowadays ,anti-sliding piles design method is mainly evolved from the method of the bridge pile foundation design. The authors summarize and analyse the processes and methods of the anti-sliding piles design used in landslide protection engineering at present. Furthermore,some problems still exposed in these methods ,especially the indeterminacy of the load acting on anti-sliding piles as well as the indeterminacy of its distribution , are canvassed, In the end, it is point out that the point of view of passive force-bearing piles should be applied to designing the anti-sliding piles. So solving all these problems will undoubtedly make those theories and methods perfect and reasonable in the process of designing anti-sliding piles.
