At present,there are two limitations in research on stability of consequent rock slope. One is the interrelation of slope and it's existent geological condition,the other is the process of deformation and undermine during artificial slope being excavated. Therefore,an in-depth study on stability of consequent rock slope is very important,and it can provide exact geological mechanical model and significant gist for stability analysis and prevention of consequent rock slope.If the method of physical simulation is use for study on stability of consequent rock slope, we can intuitionisticlly educe conclusion of point-by-point in full-court.A certain slope in Zhongjiawan segment of Hurongxi Expressway is researching object,and by way of experimentation of 9 slope models,we research the relativity between the stability of consequent rock slope and intensity of rock layer, density of cranny, obliquity of rock layer. After analyzing the phenomena and data of the experimentation, it is found: The main mode of deformation is slippage. The mode of breakage is sliding and fracturin. the process of slippage is graded. The position of coast is more hinder,the obliquity of rip face is smaller. The deformation and breakage of bedding slope firstly arises at the dig face near the earth's surface.The density is smaller, the bedding slope is more steady. The intensity of rock layer is bigger, the bedding slope is more steady.The water in rock cranny can lead to land slide. If the obliquity of rock layer is more than 45°,the bedding slope is very easy to slippage when it is excavated.After summing up the outcome of each experimentation, the rule of deformation and breakage is more analyzed. The breakage of bedding slope can be calculated as plane slippage, and the coulomb formula is fit for it.
