边坡的稳定性受到多种因素的共同影响,合理评价和预测其稳定性是边坡研究中亟需解决的课题。提出了基于改进的灰关联分析和3标度的层次分析法(AHP)相结合的边坡稳定性分析的综合方法。由改进的灰关联分析理论,得到边坡稳定性等级的关联度,根据最大关联度准则判断待测边坡的稳定性等级。该方法克服了传统灰关联分析中没有考虑稳定性评价标准中的区间形式的缺点,并利用3标度的层次分析法,对影响边坡稳定的各指标的权重进行了讨论,从而提高了灰关联分析的精度。实例分析表明,该方法能准确反映边坡稳定性状况,证明了方法是合理、有效的。
The stability of slope is affected by many factors. It is an urgent problem to be solved in slope research to evaluate and predict its stability reasonably. A comprehensive method of slope stability analysis based on improved gray relational analysis and 3-level Analytic Hierarchy Process (AHP) was proposed. By the improved theory of gray correlation analysis, the correlation degree of the slope stability grade is obtained, and the stability grade of the slope to be measured is judged according to the maximum correlation criterion. This method overcomes the shortcomings that the traditional gray relational analysis does not consider the interval form of the stability evaluation criteria and discusses the weight of each index that affects the stability of the slope by using the three-level analytic hierarchy process Accuracy of correlation analysis. The case study shows that this method can accurately reflect the condition of slope stability and proves that the method is reasonable and effective.
