摘要
利用直剪仪对玉米（水分率为11．05％、12．34％、16．72％、17．57％w．b）的内摩擦角进行了实验测定与分析。结果表明：玉米的内摩擦角变化范围是22．81°～35．20°，玉米的内摩擦角随剪切速度的增加而减小，随法向压应力的增加而减小，随水分的琏加而增加。
In this paper, the angle of internal friction of corn pile （They are produced in Nanjing in 2013. The moisture contents are 11.05%, 12.34%, 16.72% and 17.57% w. b） were measured and analyzed. The experimental results showed that the angle of internal friction of corn pile range from 22.81° to 35.20°, the angle of internal friction of corn pile decrease with the increase of normal stress and shear velocity, but in- crease with moisture content increasing.
