摘　　要：针对现有黄土湿陷性线性模糊综合评判法的不足,将其改进为非线性二级模糊综合评判法。运用非线性二级模糊综合评判法和线性二级模糊综合评判法,对高速铁路路基下8个湿陷性黄土场地的湿陷性等级做出评判,并与现场实际情况进行对比。对比结果显示:非线性二级模糊综合评判法的评判结果与实际完全相符,而线性二级模糊综合评判法的评判结果与实际不完全相符,这说明非线性二级模糊综合评判法具有合理性和优越性。According to the defect of loess collapsibility linear fuzzy comprehensive evaluation method, the pa-per puts forward an improved method, and it is nonlinear secondary fuzzy comprehensive evaluation. Using nonlinear secondary fuzzy comprehensive evaluation method and linear secondary fuzzy comprehensive evalua-tion method, the paper evaluates collapsible grade of eight collapsible loess sites under the high-speed railway subgrade, and compares it with the site actual conditions. This method is completely consistent with project practice and better than the former method. It shows that the linear secondary fuzzy comprehensive evaluation method has reasonableness and superiority.
