摘要：

Based on the dynamic, material non-linear and geometric non-linear features in soil-machine interaction, an algorithm for finite element analyses of problems in a soil-machine system was derived. Computation results of 2-D plane strain analyses by the algorithm were compared with the experimental data obtained from triaxial tests at two different axial strain rates, each under four different confining pressures. At the strain rates of 0.00019 s(-1) and 0.113 s(-1), the average R(2) for the cases of different confining pressures are 0.76 and 0.87, respectively.
