斜坡地基路堤的AHP-Fuzzy稳定性评价

斜坡地基路堤工程是一个开放复杂的“模糊系统”，影响其稳定的因素众多。现有设计方法不能全面、实际地反映路堤工程稳定的状态。应用AHP—Fuzzy综合评价法，综合考虑影响工程稳定因素的随机性、模糊性和不确定性，建立斜坡路堤AHP—Fuzzy的二级综合评价系统。采用专家打分与AHP法相结合的方式确定各因素的权重，并对实际工程进行评价。应用最大隶属度原则确定路堤的稳定性评价结果。评价结果显示该方法有较高的可靠度和判别准确度，为路堤的优化设计和稳定性防护提供依据。

AHP-Fuzzy Stability Assessment for Embankment of Foundation on Slope

The embankment of foundation on slope project is an open and complicated "fuzzy system",there are a lot of influencing factors.The existing design methods cannot fully and actually reflect the stability of embankment project.This paper establishes a class 2 comprehensive assessment system for AHP-Fuzzy stability of the embankment on slope by using AHP-Fuzzy comprehensive assessing method to consider randomicity,fuzziness and nondeterminacy of factors influencing the project stability.In the paper,the combination between marking by experts and AHP method is adopted to determine the weights of various factors and assess the actual project.The maximal membership grade rule is applied for determining the results of assessing the stability of embankment.The results show that the method is highly reliable and accurate for discrimination,providing the basis for optimal design and stability protection of the embankment.
