抗滑桩设计的简化方法

The Simplified Design Methodology of Slide-resistant Pile

通过对抗滑桩的常用设计计算方法进行比较,指出其在某些方面的不足,从而提出了抗滑桩设计的简化方法:将抗滑桩当作悬臂梁,根据力的相互作用原理,在假定滑坡推力值的作用点、作用方向以及抗滑桩截面尺寸和配筋的条件下,即可计算出桩所承受的滑坡推力值,进一步可确定边坡增加的稳定系数及其桩距,从而完成抗滑桩的整个设计.

This article compares several methods commonly used for designing resistant-slide pile and points out their flaws in certain aspects. A simplified method is put forward：by using the resistant slide pile as cantilever beam, according to the principles of interaction and under the conditions of functional spot and functional direction of slide thrust value, the resistant-slide cross-seetion size and reinforee-ment, the slide thrust value which the pile can bear can be calculated. Meanwhile, the slope stability factor can be determined. As a resut, the whole design of resistant-slide pile is completed.
