摘要
利用剪切仪,测定了在不同的剪切速度、不同的法向压应力、不同的水分条件下大豆的内摩擦角。结果表明:随着剪切速率的增大(1.33~4.33 mm/min)大豆内摩擦角减小,随着法向压应力的增大(0.25×105~1.00×105Pa)大豆内摩擦角减小,随着水分含量的增大(12.11%~18.02%)大豆内摩擦角先增大后减小。
In different shear velocity,different normal stress and different moisture content,the internal friction angles of soybean were measured by direct shear apparatus.The results showed that the internal friction angle of soybean decreased as shear velocity increased(1.33~4.33 mm/min)and normal stress increased(0.25×105~1.00×105Pa),the internal friction angle of soybean increased at first and then decreased as moisture content increased(12.11%~18.02%).
