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.
