| 摘要: |
| 采用大变形有限元和简单的接触面理论，数值模拟了静力触探的探入过程．比较了用弹性模型、修正的剑桥模型和砌块体模型的大变形模拟计算结果，表明考虑土体结构强度的砌块体模型的大变形模拟结果较优． |

| Abstract: |
| The cone penetration process is numerically simulated by using the large-strain finite element method and a simple theory of interface. The calculation results of the elastic model, modified Cam-clay model and masonry model with large strain are compared. It can be seen that the simulation results of the masonry model considering the structural strength and large strain of soil are the best. |
