摘要
分析红沙泉煤矿外排土场边坡稳定性影响因素为目的,结合边坡地质条件和岩石力学参数,运用基于极限平衡理论的Geo-studio软件分析边坡的潜在滑移面及滑坡模式,计算边坡的安全系数,并分析各因素对边坡稳定性的影响规律。研究结果表明:边坡的滑坡模式为圆弧形滑动;当排弃至第5台阶时,安全储备系数为1.215;边坡稳定性随着含水率的增加而降低,随着边坡倾角的增加而降低,随着排弃高度的增加而降低。
The article analyzes the factors of aflecting the slope stability- in the external dump of the Hongshaquan Coal Mine. Combining slope geological conditions and rock mechanics parameters, based on the limit equilibrium theory, the article uses Geostudio software to analyze the potential slip surface and landslide mode of the slope, calculates safety factor of slope, and analyzes the influence law of various factors on slope stability. The resuhs show that the landslide mode of the slope is circular arc sliding, when discarded to the fifth step, the safety reserve coefficient is 1.215; the slope stability-decreases with the increase of water content; decreases with the increase of slope angle; decreases with the increase of the discarding height.
