基于FLAC3D的水库碎石土边坡抗滑桩加固效果研究

Research on Reinforcement Effect of Anti-slide Piles of Reservoir Gravel Soil Slope Based on FLAC3D

碎石土体边坡稳定性差,易失稳滑坡,造成严重的地质灾害。文章以水库碎石土堆积体边坡为研究对象,采用有限差分FLAC3D模拟软件分析抗滑桩加固前、后边坡稳定性变化。结果表明边坡经抗滑桩加固后,边坡水平和竖直变形显著下降,抗滑桩加固效果较好。研究结果为碎石土边坡抗滑桩加固设计提供参考。

The stability of gravel soil slope is poor.It is easy to destabilize and landslide,resulting in serious geological disasters.In this paper,the slope of gravel soil accumulation in reservoir is studied by using finite difference FLAC3D simulation software to analyze the slope stability changes of slope before and after anti-slide pile reinforcement.The results show that the horizontal and vertical deformation of the slope decrease significantly after the anti-slide pile reinforcement,and the anti-slide pile reinforcement effect is better.The research results provide reference for the design of anti-slide pile reinforcement of gravel soil slope.
