在滑坡治理工程中,抗滑桩是一种重要的支挡加固措施,在确定滑坡推力后,如何准确、合理地计算抗滑桩内力对滑坡治理工程的成败常常有着决定性的作用;根据滑动面以上桩身滑坡推力的分布形式、桩前剩余抗力的分布情况以及桩身边界条件,将“m”法和“K”法相结合,推导出全桩内力有限差分计算公式;所提出的计算方法思路简明、计算精度高,在实际滑坡治理工程中得到了有效的应用,也可应用于其他横向受力桩的分析与计算。
In landslide control project, anti-slide pile is an important support reinforcement measures, after determining the landslide thrust, how to accurately and rationally calculate the internal forces of anti-slide pile is often decisive for the success or failure of landslide control project. According to the sliding surface Based on the distribution of thrust of pile body landslide, the distribution of remaining resistance before pile and the boundary condition of pile body, the finite difference formula of internal force of pile is deduced by combining “m ” method with “K ” method. The calculation method is concise, the calculation accuracy is high, and it is effectively applied in the actual landslide control project. It can also be applied to other lateral pile analysis and calculation.
