| 摘 要： | 在分析总结现有土钉及其与上体粘结滑移的工作性能试验研究基础上，建立土钉及其与土体粘结滑移的有限元模型，经推导给出单元刚度矩阵显式，并直接用于进一步的有限元分析。工程实例计算表明，基坑水平位移和土钉最大拉力与实测结果基本吻合。

| Abstract: | On the basis of summary and analysis on the experimental investigation associated with soil nails and their adhesion-slip interaction with soil, the models of soil nails and their adhesion-slip interaction with soil were erected and the element stiffness matrices were derived in direct formulations. Furthermore, the matrices were incorporated directly in the finite element analysis of soil nailed structures, and the analySis results of an engineering case were presented. The agreement between the measured and the predicted movements is good. |
