山谷型尾矿库建设中,边坡稳定性评价分析成为重要的内容。该文介绍了地层、构造、地下水、地震力、坡角等影响边坡稳定性的因素,分析了各因素对边坡稳定性影响的机理和作用。同时通过工程实例,利用二维边坡稳定性计算软件,分别计算各因素作用下边坡的安全系数,分析计算边坡稳定性对影响因子的敏感度,确定主要的影响因素,为合理化施工建设提供了可靠的依据。
In the construction of valley-type tailings pond, the evaluation and analysis of slope stability becomes an important content. This paper introduces the factors that affect the stability of the slope, such as stratum, structure, groundwater, seismic force and slope angle, and analyzes the mechanism and effect of various factors on the stability of the slope. At the same time, through the engineering example, using the two-dimensional slope stability calculation software, the safety factor of the slope under each factor is calculated, the sensitivity of the slope stability to the impact factor is analyzed and calculated, the main influencing factors are determined, and the rational construction is provided Reliable basis.
