劣化扰动因素下尾矿库边坡地质灾害预警及边坡稳定性分析

高陡岩质边坡的稳定性历来备受国内外学者的广泛关注，也是近年来最主要的地质灾害之一，尤其是复杂地质条件下的高陡岩质边坡更是如此，若在此条件下参与了人工开挖，那么边坡的稳定性和导水性均会产生显著的变化。在此条件下采用3DMine、FLAC^3D数值模拟软件、Origin后处理软件以及室内岩石力学试验等方法研究了复杂地质条件下某尾矿库3个剖面的高陡岩质边坡的稳定性，研究结果显示Ⅰ-Ⅰ剖面和Ⅱ-Ⅱ剖面虽然边坡底部存在最大剪应变，但其安全系数均满足规范要求，其边坡处于稳定状态，且其边坡表面的最大主应力均分布在0.1 MPa左右，不会产生明显的应力变化。研究结果为今后尾矿库的建设和边坡的维护提供了科学依据，并能够很好的为尾矿库边坡的地质灾害提供安全预警。

Geological hazard warning and slope stability analysis of tailings pond slope under degradation disturbance factors

The stability of high and steep rock slopes has always been widely concern by scholars at home and abroad. It is also one of the most important geological disasters in recent years, especially the high and steep rock slopes under complex geological conditions. If manual excavation is involved under such conditions, the stability and water conductivity of the slopes will change significantly. Under this condition, the stability of high and steep rock slopes of three sections of a tailings pond under complex geological conditions is studied by using 3DMine, FLAC3D numerical simulation software, origin post-processing software, and indoor rock mechanics test. The research results show that although there is a maximum shear strain at the bottom of the slope at sections I-I and section ii-ii, their safety factors meet the requirements of the specifications, and their slopes are in a stable state, And the maximum principal stress of the slope surface is distributed around 0.1 MPa, and no obvious stress change will occur. The research results provide a scientific basis for the construction of the tailings pond and the maintenance of the slope in the future and can provide a good safety warning for the geological disasters of the tailings pond slope.
