露天高陡边坡角优化设计及稳定性分析

UDY ON THE OPTIMIZATION OF THE SLOPE ANGLE AND ABILITY OF HIGH EEP OPEN PIT SLOPE

将数学中的二分法理念引入用于边坡角度的优化设计,给出了边坡角度的优化设计流程。运用此方法对首钢水厂铁矿露天高陡边坡具有代表性的剖面进行了边坡角度的优化设计,并结合有限差分数值计算方法对不同优化角度的边坡进行了稳定性分析,推荐出边坡的最佳优化角度。

The idea of dichotomy method is used to optimize and design the slope angle and the process of the optimization is given. The presented paper employs dichotomy method to design the slope angle of the representative slope in Shuichang high eep open pit in Shougang iron mine and adopts FLACZD to analyze the ability of the slope with this angle. The optimization angle of the slope in the example is provided.
