摘要
针对工程滑坡中岩土性质的具体情况,假定地基系数满足线性增长规律,考虑桩身自重的影响,得出斜向锚索荷载、滑坡推力以及锚固段抗力共同作用下的抗滑桩计算分析的有限杆单元分析计算方法。结合具体实例,对上述方法进行了验证,同时探讨了在无预应力锚索和不同锚索力作用下抗滑桩的受力特性。分析结果表明,预应力锚索的使用对抗滑桩的受力状况有较大的改善,并且施加于锚索上的预应力为0.3倍剩余下滑力时,抗滑桩的受力最合理。
By analyzing geotechnical characteristic in landslide, foundation modulus was assumed to satisfy linearity rule and with influence of pries＇ own weight taken into consideration simultaneously, a kind of finite element method （FEM） was developed for anti- slide pile working with inclined anchoring force load, landslide thrust and anchoring resistance together. The method was verified with practical engineering and the results under the conditions of no anchor cable and different anchor- hold were compared, which shows that prestressed anchor gives big amelioration to anti - slide pile . and working status of anti - slide pile is rational of when the anchoring force is 0.3 times of surplus slide force.
