文章针对黄土的湿陷性受多因素的影响特点,以大量室内压缩试验和现场浸水试验资料为基础,利用模糊综合评判理论,提出了湿陷性黄土湿陷性等级别的模糊综合评判方法,其中权重的确定采用了主观和客观相结合的原则,隶属函数形态的确定以实测资料的统计分析为基础。工程实例验证,应用该方法确定的湿陷系数相对误差小于10%,表明该方法更客观、全面、精度高,能满足公路建设的精度要求。 In this paper, according to the characteristics of loess collapsibility affected by many factors, based on a large number of indoor compression tests and field immersion test data, a fuzzy comprehensive evaluation method of collapsible loess collapsibility level is put forward based on fuzzy comprehensive evaluation theory. The weight is determined by the combination of subjective and objective principles. The determination of the membership function is based on the statistical analysis of measured data. The engineering example shows that the relative error of collapse coefficient determined by this method is less than 10%, which shows that this method is more objective, comprehensive and accurate and can meet the precision requirements of highway construction.
