摘　　要：文章以实际工程为研究对象,对滑坡稳定性以及治理措施等方面进行了深入的分析。分析结果表明现状滑坡在暴雨工况下存在滑动破坏的可能性;根据稳定性分析结果及滑坡现状确定了“削方+格构护坡+截排水沟+抗滑桩+挂网喷浆”的治理方案,并论述了该方案的细节;结合BP神经网络建立了滑坡变形预测模型,通过该模型对滑坡未来变形趋势进行预测表明,该滑坡在60周次时最大变形为22.81 mm,小于25 mm的变形限值,且变形呈现收敛趋势,说明该滑坡治理方案的合理性。In order to further improve the quality of landslide control in the process of highway engineering construction,this paper takes the actual project as the research object,and makes an in-depth analysis of landslide stability and control measures.The analysis results show that the current landslide has the possibility of sliding failure under rainstorm conditions.Then,according to the results of stability analysis and the current situation of landslide,the treatment method of'cutting+lattice slope protection+intercepting drainage ditch+anti-slide pile+hanging net spraying'is determined,and the details of the scheme are discussed.Combined with BP neural network,a landslide deformation prediction model was established.The model was used to predict the future deformation of the landslide.The maximum deformation of the landslide was 22.81 mm at 60 cycles,less than the deformation limit of 25 mm,and the deformation showed a convergence trend,indicating the rationality of the landslide control scheme.The research content of this paper provides some engineering reference for the follow-up related work.
