摘要:
 在考虑爆破振动的影响下,建立露天矿山台阶边坡发生平面滑动的计算模型,推导出了最不利滑面倾角和最小稳定系数的解析解。通过对解析式中参数敏感性分析发现:对多台阶露天矿山稳定影响因素从高到低分别是台阶高度、坡面角、粘聚力、内摩擦角、平台宽度。边坡的稳定系数随着台阶高度和坡面角的增大而减小,随着粘聚力、内摩擦角和平台宽度的增大而增加。工程实践中的应用表明推导出的解析解具有较强的实用性。
Abstract:
 Considering the influence of blasting vibration, the calculation model of plane sliding of multi-step slope in open pit mine is established, and the analytical solution of the most unfavorable sliding surface inclination and the minimum stability coefficient is derived. Through the sensitivity analysis of the parameters in the analytical formula, it is found that the influencing factors for the stability of multi bench open pit mines from high to low are bench height, slope angle, cohesion, internal friction angle and platform width; the stability coefficient of slope decreases with the increase of bench height and slope angle, and increases with the increase of cohesion, internal friction angle and platform width. The application in engineering practice shows that the analytical solution has strong practicability, which can provide reference for similar open-pit mine slope design.
