摘　　要：使用TSZ-6A型应变控制式三轴仪对不同围压(8kPa^200kPa)、不同含水率(9.8%、11%、13.5%、14.8%、15.8%w.b.)的黑龙江省大豆堆的体积变化和体变模量进行了测定,分析了围压与含水率对大豆堆体变模量的影响。体变模量随着围压(8kPa^200kPa)的增大而增大,大豆实验结果表明:对含水率为9.8%w.b^15.8%w.b、围压为8kPa^200kPa的大豆堆,其体变模量范围为227.94kPa^610.58kPa。相同含水率的大豆堆的体变模量随着围压(8kPa^200kPa)的增大而增大;同一围压下,大豆堆体变模量随着含水率(9.8%w.b^15.8%w.b)的增大而减小。In this paper, bulk strain modulus of soybean pile（moisture contents are 9.8%, 11%,13.5%, 14.8%, 15.8%w. b. and confining pressures are from 8 kPa to 200 kPa. ） are measured by the strain control type three triaxial apparatus. The influences of the confining pressure and the moisture content on the bulk strain modulus of soybean pile had been analyzed. The results showed that the bulk strain modulus of soybean pile ranged from 227.94 kPa to 610.58 kPa in the moisture contents range of 9.8%-15.8%w. b and the confining pressure range of 8 - 200 kPa. The results also showed that as confining pressure （8 - 200kPa）increases the bulk strain modulus of soybean pile increase in the same moisture content and as moisture content of soybean pile （9.8-15.8%w. b） increases the bulk strain modulus of soybean pile decrease under the same confining pressure,
