摘要
火烧区对边坡稳定性的危害较大,针对某露天煤矿南帮火烧区的边坡,分析了火烧区岩石力学特征及积水对边坡稳定性的影响,根据实验数据提出岩土体物理力学指标推荐值,并用FLAC3D软件对火烧区边坡进行了稳定性数值计算。结果表明:南帮边坡破坏模式为切层滑移型,建议边坡角25°.
The fire area has great harm to slope stability. The paper mainly researches on the slope of south fire area of an open-pit coal mine. analyzes the mechanics characteristics and the influence of the fire zone rock and water on the slope stability. According to experimental data,physical and mechanical indicators of rock and soil has been put forward and recommended with FLAC3 D software to calculate the stability of the slope. The result showed that the failure mode of south slope is cutting slip and 25° of the slope Angle is suggested.
