摘要
本文根据块体理论使用矢量分析方法结合全平面赤平投影方法对某矿的边坡稳定性进行了分析,着重讨论了反倾断裂面时,在边坡稳定性分析中所起的作用.结果表明,当坡体内同时存在顺坡和反倾断裂面在开采过程的有限时间内,相对仅有从而顺坡断裂面存在的条件,可改善边坡的稳定性.定量的计算表明可提高边坡角7°～8°,描述了反倾断裂面对边坡稳定性的改善程度和特征.
Based on block theory, this paper has made ah analysis of slope stability for a mine with combined method of vector analysis and stereographical projection, and has emphatically made a discussion on the role played by reverse inclined fracture face in slope stability.
According to analysis, the slope, in which, both favoring grade and reverse inclined fracture face exist,is more stable than the slo'pe which keeps favoring grade fracture face only.From quantitative calculation,the slope angle can be increased by 7-8°.?
