摘　　要：结合公路的结构特点 ,依据湿陷性黄土的力学性质 ,确定了湿陷性黄土的分类指标 ;根据甘肃省主要地区的实测黄土湿陷系数及其分布规律 ,进行了甘肃省湿陷性黄土的分类和区域评价 ;The indices of classification of collapsed loess are determined according to the structure characteristics of the road and the mechanics characteristics of the collapsed loess firstly.Then the loess' collapse in the collapsed loess region in Gansu is evaluated by regions according to the coefficient measured actually of Loess' collapse in main region and its law of distribution. Finally, type map of the distribution of collapsed loess is drawn.

关 键 词：湿陷性黄土 分类指标 区域评价 分布图
