| 摘 要： | 评判指标的选取是影响膨胀土胀缩等级分类的一个重要因素,基于灰色理论中灰色关联分析法和灰色聚类法,采用标准吸湿含水率、塑性指数、自由膨胀率三个反映膨胀土本质特性的指标来判定膨胀土的胀缩等级,并与其它方法对比分析,其计算结果与实际膨胀潜势基本吻合,验证了灰色理论在膨胀土胀缩等级分类中的合理性。

| Abstract: | In this paper, based on gray theory, selected to reflect the expansion of the basic characteristics of soil free swell rate, plasticity index, the standard SMA was discrimination index, the use of gray relational analysis method and gray clustering method to determine the swell-shrink grade of expansive soils, and other comparative analysis of the calculation results and the actual swelling potential agreement, verify that the gray theory in the expansion of the rationality in the soil swelling and shrinkage classification. |
