| 摘 要： | 集对分析是一种用联系度处理不确定性问题的系统分析方法。提出将模糊联系度的思想应用到差异度系数的取值 中，充分挖掘所研究系统中的有效信息，使得对系统的评价和决策更加准确和合理。将此改进的集对分析方法应用于黄土路堑边坡稳定性评价中，并与其他方法进行对比，表明该方法简便、有效。

| Abstract: | Set pair analysis(SPA) is a system analysis method for solving of indeterminate problems with connection degree.The concept of fuzzy connection degree is applied to determine the value of discrepancy coefficient.As a result,more information can be utilized,and the results are more accurate and reasonable.This method is applied to assess the stability of loess cutting slope.The results from practical example with other methods show that it is simple and effective. |

| Keywords: | cutting slope stability set pair analysis discrepancy coefficient fuzzy connection degree |
