摘    要:根据相似理论建立地质力学模型,介绍了模型试验的设计和过程。通过4组对比试验,研究了原型边坡的变形破坏机制以及改变边坡岩体的岩层倾角对边坡稳定性的影响。试验结果表明,顺层边坡的主要变形方式均为滑动变形,破坏模式为滑移-拉裂破坏,滑动过程为分级滑动,越往后拉裂面倾角越小。边坡的变形破坏首先发生在临空面靠近地表部位。层面强度越大,边坡越稳定;岩层倾角越小,边坡越稳定。

关 键 词:顺层岩石边坡  物理模型试验  岩层

Abstract:Based on simulation theory,a geomechanical model is established.The paper introduces the design and process of the experimentation.By way of experimentation of 4 slope models,we study the stability of archetype slope,the correlation between the stability of consequent rock slope and obliquity of rock layer.After analyzing the phenomena and data of the experimentation,it is found that the major deformation model is slippage.The mode of breakage is sliding and fracturing.The process of slippage is graded.The more hinder the position of coast is,the small the obliquity of rip face is.The deformation and breakage of bedding slope firstly arises at the dig face near the earth's surface.The bigger intensity of rock layer is,the steadier the bedding slope is.The small the obliquity of rock is,the steadier the slope is.
Keywords:Consequent rock slope  experimentation of physical model  obliquity of rock layer
