摘　　要：采用风干法与冻干法分别对不同深度土层的土体进行干燥制样,利用压汞试验得到的孔隙分布曲线,结合不同土层土体的特点,分析了土体经过风干法与冻干法干燥制样后存在的差异性,得出了适用于风干法制样的土体特点。The different depth soil layer soil body was prepared after drying with air dry method and freeze dry method,with the pore distribution curve obtained form mercury intrusion test,combined with different soil layer characteristics,the difference of soil prepared by air dry method and freeze dry method was analyzed,the soil body characteristics applied to air dry method preparation was obtained.
