摘要
该文基于相似模型试验,结合现场地质资料及监测数据,探究不同锚固角下软硬互层倾倒边坡的变形破坏特征,评价不同锚固角的锚固支护效果,确定与倾倒变形体破坏特征相适应的最优锚固方案。通过试验发现,无论采取何种方式进行锚固,均能不同程度地降低模型的破坏程度,这表明锚固角对边坡模型的变形特征和支护效果有直接的影响。
In this paper,based on similar model tests,combined with on-site geological data and monitoring data,the deformation and failure characteristics of soft-hard interbedded toppling slope under different anchorage angles are studied,the anchoring support effect of different anchoring angles is evaluated,and the optimal anchoring scheme that is suitable for the failure characteristics of toppling deformation body is determined.Through the experiment,it found that no matter what kind of anchoring method is adopted,the failure degree of model all can be reduced to some extent,which shows that the anchoring angle has a direct impact on the deformation characteristics and support effect of slope model.
