摘要: 针对影响黄土路堑高边坡稳定性因素的复杂性和模糊性,将可拓工程方法与路堑边坡稳定性评价相结合,通过参数正交试验分析确定权重,提出了路堑边坡稳定性评价的物元关联函数及物元关联度的计算方法。建立了适合可拓学理论的边坡稳定性分类标准,实现了定性与定量评价黄土路堑边坡的结合。实例评价结果与定值计算、工程实际调查吻合良好。

Abstract: Focused on complexity and confusion of factors influencing stability of loess slope of cut, this paper analyzed the calculation means of connective function and dependent degree in the appraise of slope of cut stability, and establish the classification criteria of slope of cut stability which is adapted to extension theory, combined with the topology engineering method and the stability assessment of loess slope of cut.The example evaluation consequence agrees with the result of fixed value calculation and project reality investigation.The assessment method of slope of cut stability based on extension theory presents a new feasible path for the problem which can settle stability assessment of the slope of cut.
