摘要
使用三轴仪对小麦粮堆弹性模量进行测定,通过预实验结果的分析比较,确定了几个实验条件(滞回圈圈数、加卸载间隔时间、轴向压力)。在不同的围压下测定小麦粮堆弹性模量,其范围为:314.2 kPa^902.1 kPa,由实验结果拟合出围压与小麦粮堆弹性模量的关系方程。
Elasticity modulus of wheat bulks was measured by triaxial apparatus, and three key experimental factors were determined by analyzing the data of pre--experiments, such as number ot hysteresis loop, time interval of loading and unloading, vertical pressure. In different confining pressures, elasticity modulus of wheat bulks was measured and its range was from 314.2 kPa to 902.1 kPa. Based on the experimental resuits, the relation equation on confining pressure and elasticity modulus was fitted.
