为了能够对白云东矿的边坡安全进行研究,采用FLAC3D为数值模拟计算工具,通过采用强度折减法对边坡的稳定性进行模拟计算。最终得出白云东矿由于地层多为白云岩或长石板岩,岩性较为坚硬,纵然边坡角度达到45°,其边坡安全系数仍然达到2.5以上,说明不具备大面积滑坡等风险;但是考虑到岩石的蠕变以及岩石风化等降雨因素,决定采用植物群落固坡实现边坡的稳定与安全。
In order to study the slope safety in Baiyundong mine, FLAC3D is used as a numerical simulation tool to simulate the stability of the slope by using the strength reduction method. As a result, most of the strata are dolomite or feldspar, and lithology is relatively hard. Even though the slope angle reaches 45 °, the safety factor of the slope is still above 2.5, indicating that there is no risk of large-scale landslides. However, Taking into account the rock creep and rock weathering and other rainfall factors, it is decided to adopt the slope stability of plant communities to realize the stability and safety of the slope.
