摘　　要：对粘性土壤进行了粘弹塑性分析和加载试验,建立了粘土的力学模型.编制出了螺旋滚筒在粘土上推进力的计算程序,在试验室条件下对螺旋滚筒产生的推进力进行了实测,计算值与实测值对照,两者比较一致.A mathematical model reflecting the stress-displacement relationship of saturated clay soil is derived from visco-elastic and plastic analysis. The values of the rheological coefficients in the model are found from experiments. Based on the model,a computer program is achieved to calculate the tractive force of a screw. It was abserved an agreement between calculated data and measured data.
