Abstract

A study on distribution characters of initial stress in the condition of gravity effect in the slopes within alp of which the slope angles poses 30° 45° 60° respectively were conducted by numerical analysis. After comparison, it is found that when closing to the region of slope surface, the difference of vertical stress between the value which are calculated by the direct buried depth and the actual value is huge. And the difference becomes huger with the slope becoming steeper. Then , a comparison has been made with excavating a cavern which poses 3 different positions separately at different distance from the slope toe in the condition of 45° slope angle and using the equivalent mechanical parameters of jointed rock mass to make numerical analysis to look the rock stability difference of the three schemes. It is found that the closer to slope surface (slope toe), the larger the plastic zone or the damage zone around the caverns becomes.
