摘要
文章采用赤平投影分析和块体离散单元法,分析高陡岩质边坡岩体内不同结构面组合类型对边坡稳定性的控制作用,分析表明该边坡在地震作用下的主要破坏模式为坡体上部局部小规模楔形体滑移破坏,主控该边坡稳定性的最危险结构面组合为J2J3结构面组合。
The paper analyzes the control actions of different combination types of structural planes in high-steep slope rock to the slope stability using the stereographic projection analysis and the block discrete element method. The analysis shows the main destroy mode of this slope under earthquake is local small scale wedge slip failure of the upper part of the slope, and the most danger structural planes combination witch is the main controlling one is the J2J3 combination.
