摘要:
通过对某水电高边坡右岸变形体的岩体组合、顺层边坡特点、岩体特性以及变形迹象分析，以岩体结构调查为基础，建立了地质模型，在此基础上通过FLAC3D数值模拟，对其变形破坏机制进行了深入探讨。结果表明，边坡主要是沿层面以蠕滑-拉裂变形为主，变形体边界受层间软弱夹层及岩体结构面控制，坡体中上部块体沿层间软弱夹层产生滑动，受下部岩体约束，在锁固段局部弯曲变形，同时上部岩体产生拉裂变形，在此基础上形成累进破坏；受上部岩体推力作用，边坡碎裂岩体中逐渐产生剪切滑动面，并与弯曲部位岩体中滑移切出面贯通，可能形成最终破坏。基于变形体的破坏模式，对变形体的稳定性进行分析，提出了对变形体锁固段采用锚索强加固的措施。
Abstract:
By the rock mass combination,bedding slope characteristic and rock mass features of a hydropower plant right bank slope,based on analyzing the deformation indication and the rock mass structure survey,then geological model was established.The deformation failure mechanism was discussed thoroughly by the FLAC3D numerical simulation.The results indicated that the slope deformation mainly is characterized as creeping-ripping along the bedding surface,the deformation body boundary is controlled by soft rock strata and rock mass structure,middle and upper part of slope slide along weak intercalated layer,the locked section appear local bending and deformation because lower rock mass is restricted,at the same time,upper rock mass appear fracture deformation and based on the process form progressive destruction;By the upper rock mass thrust,in fragmentation rock mass form shear sliding surface gradually and run-through with the slip-cut face of bending parts,and then may form the final destruction.Based on the failure model,the stability of deformation body was analyzed,and then the measures that adopt to anchor to reinforce the locking segment was proposed
