摘要
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。
The evaluation and analysis on the slope stability is the important job in the construction of valley-shaped tailings reservoir. This paper introduced the factors such as stratum, texture, underground water, seismic force and slope angle etc. which influencing the slope stability, and analyzed each factor mechanism and effect which influencing the slope stability. Meanwhile, using the actual projects as ex- ample, the slope safety coefficients under each factor influence were calculated by means of two-dimen- sional slope stability calculation software, and the sensitivity of slope stability to influencing factors is an- alyzed and calculated, so the main influencing factors are determined, and it provids the reliable refer- ence for reasonable construction.
