针对边坡稳定性影响因素复杂、传统的稳定性分析方法计算工作量巨大、计算过程复杂的问题,提出了一种新的解决方法——判别分析方法.以在边坡稳定性分析中广泛采用的边坡重度、内聚力、摩擦角、边坡角、边坡高度、孔隙压力比共六项指标作为判别因子,建立了可进行边坡稳定性预测的判别分析模型.典型工程实例的分析结果表明,该方法简便可行,具有较强的分析可靠度,且排除了边坡稳定性判别分类中人为因素的影响,为解决边坡岩体稳定性判定和分类提供了一条新的途径,可以在实际工程中进行推广.
In view of the complicated factors affecting slope stability and the traditional method of stability analysis, which is computationally intensive and computationally complex, a new solution method, Discriminant Analysis, is proposed, which is widely used in slope stability analysis Of the slope of the heavy, cohesion, friction angle, slope angle, slope height, pore pressure ratio of a total of six indicators as a discriminant factor to establish a slope stability prediction model can be identified.Analysis of typical engineering examples show , The method is simple and feasible, has strong analytical reliability, and ruled out the impact of human factors in the slope stability classification, which provides a new way to solve the slope rock mass stability judgment and classification, Project promotion.
