| 摘 要： | 作者将各向异性弹塑性模型引入到比奥固结理论有限元法中，对深基坑开挖进行了考虑土体各向异性的分析和模拟计算，并通过一深基坑工程实例，对深基坑开挖过程中所引起的基坑周围水平、竖向位移等进行了计算，并将计算结果与不考虑土体各向异性的情况及实测结果进行了比较。

| Abstract: | In this paper the elastic plasticity anisotropie model is introduced into the finite element of the Biot consoliclarion theory. The calculation and the measurement of the lateral and vertical displacement around the deep pit during it excavation are compared. The analysis with isotropic elastic plasticity model for a deep pit has also been made. |
