针对目前常用的综合评价模型只能确定边坡稳定性所在等级,不能评价边坡稳定性在所属等级中的好差程度的问题,考虑指标动态权重对边坡稳定性的影响,改进了理想点法,通过引入均衡函数的变权公式,提出了可变权重理想点法,并将该方法应用于四个边坡的稳定性综合评价中。结果表明,可变权重理想点法与灰色关联分析和可拓方法的评价结果基本一致,能够比较精确地确定边坡所属稳定性等级,而且可以确定同一等级内不同边坡稳定性的差别。
According to the commonly used comprehensive evaluation model, the grade of slope stability can only be determined, the difference of slope stability in the grade can not be evaluated, and the influence of dynamic weight on slope stability is considered, and the ideal point Method, a variable weight weight point method is proposed by introducing the variable weight formula of the equilibrium function, and the method is applied to the comprehensive evaluation of the stability of the four slopes. The results show that the results of variable weighting ideal point method and gray relational analysis and extension method are basically the same, which can determine the stability level of the slope more accurately and determine the difference of the stability of the different slope within the same grade.
