根据边坡实际地质模型 ,基于弹塑性与粘弹 -粘塑性理论的本构方程 ,通过有限元模拟分析 ,定量地揭示和模拟再现了高边坡岩体破裂、变形、破坏及失稳前后锁固段岩体渐进性破坏的机制和过程 ,探讨了高压水流作用下滑坡启程剧动的破坏机理。 According to the actual geologic model of slope and the constitutive equations based on elasto-plasticity and viscoelastic-viscoplastic theory, the finite element analysis and simulation reveal and quantitatively reveal the fracture, deformation, failure and instability of the high slope rock mass before and after the lock The mechanism and process of progressive failure of rock mass in fixed section are discussed. The failure mechanism of landslide departure is discussed under the action of high pressure water flow.
