    DESIGN OPTIMIZING OF ANTI-SLIDING PILE WITH PRESTRESSED CABLE ANCHORS

    • 摘要: 锚索抗滑桩与普通抗滑桩相比,其受力状态更加合理。本文通过建立合理的计算模型和计算简图,推导出锚索在桩身任意位置的计算公式,并编制程序实现弯矩和应力的计算,确定出最优的锚固角和最优的锚索位置,可以有效减小抗滑桩的弯矩,更加充分的发挥锚索的作用。文中最后结合延安宝塔山滑坡治理,给出了实际应用结果。

       

      Abstract: The technique of anti-sliding piles with prestressed cable anchors is an effective measure in landslide treatment.Compared with common anti-sliding piles,anti-sliding piles with prestressed cable anchors result in a more reasonable force bearing state.This paper,on the basis of simple hypothesis,presents the physical model and computing diagram of piles with with prestressed cable anchors,derives the anchor in the pile body free position formula,establishes a simple procedure realization moment and stress computational scheme.This method can be used to determine the most superior anchor angle and the most superior position,which will effectively reduce the anti-slide pile moment and fully display anchor function.Finally,a case of the BaoTa mountain of Yanan landslide treatment is given and the practical result is discussed.
