摘要

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

Abstract

The stability of slope is influenced by multiple factors. It is one important subject to evaluate and predict the stability reasonably in the research of slope. Based on the approved grey correlation analysis and analytic hierarchy process (AHP)

the comprehensive method is proposed to analyze the slope stability. According to the principle of grey correlation analysis

associate degree of slope stability is estimated and the slope grade is appraised by maximum correlation law. This method avoids the disadvantage that interval of the grade standards is not taken into account in traditional grey correlation analysis. The AHP of scale 3 is used to discuss the index weights; and precision of grey correlation analysis is improved. Case study shows that this method is reasonable and feasible to estimate slope stability.
