摘要
对现有膨胀土判别与分类方法进行了评价,对反映和表征膨胀土胀缩机理和特性的指标进行深入探讨。最后建议用fisher判别分析方法进行膨胀土的判别与分类,并建议用反映膨胀土胀缩性、强度特征的指标来验证分类结果。
The first problem that should be solved in construction in expansive soil region is the identification and classification of expansive soils. The existing approach to identification and classification of expansive soil has been evaluated. The indices that can reflect and characterize swell-shrink mechanism and property were analyzed. Finally, the fisher＇s discriminant analysis method for identification and classification of expansive soil is proposed and a approach validating the results with the indices that characterize the swelling-shrinkage and strength of expansive soil is suggested.
