摘要
对农业土壤的抗剪强度试验研究表明 :在土壤含水量一定的情况下 ,抗剪强度随土壤所承受的垂直压力的增加而线性增大 ;抗剪强度随含水量的增加而非线性减小。分别确定了土壤抗剪强度与垂直压力、含水量之间的关系 ,建立了土壤抗剪强度 -垂直压力
The resistance to shear of agricultural soil was studied. Results showed that the resistance to shearing 1inear corre1ation of agricu1tural soil increases with the vertical stress under certain condition of soil moisture capacity and decreases with the increasing of soil moisture capacity. The relation of resistance to shear with vertical stress and moisture capacity determined separately, and an mathematical model among soil resistance to shear, vertical stress and moisture capacity was instituted
