摘要:
基于矢量和法的矿山边坡稳定分析方法在边坡的荷载和滑面已知的情况下,运用有限元法计算滑裂面上的真实应力分布,得出滑裂面上各处静滑动摩擦力合力方向的反方向即安全系数的计算方向θ,并在此方向上由抗滑力与滑动力的矢量和得出矢量法安全系数F(θ).本文运用矢量分析法计算出大冶东露天采场F9断裂带内某边坡的安全系数,将计算结果与极限平衡法和有限元强度折减法计算结果进行了分析和比较,分析表明该法与已得到工程验证的有限元强度折减法模拟该边坡渐进破坏的定向分析结果相吻合,说明了矢量分析法的可行性和工程实用性.
Abstract:
The vector sum analysis method based on mine slope stability analysis is under the case of known load and the sliding slope surface slope, and the use of the finite element method to calculate the real stress distribution of the sliding surface throughout the obtained static friction force of slip sliding surface in the opposite direction for the direction of the calculation of safety factor θ, it defines the vector method safety factor F (θ) in terms of the vector characteristics of force against and driving sliding in θ. In this paper, the vector analysis method is used to calculate the Daye open pit F9 east of a fault zone safety factor, then analyzed and compared the result with the known result calculated from gravity increase method and strength reduction finite element method. The analysis showed that the results are coincident with qualitative analysisfinite element strength reduction simulating the gradual damaging process of the slope, and illustrates the feasibility and the engineering practicability of vector analysis method.
