| 摘 要： | 土钉墙支护是1种经济、安全、可靠的基坑支护型式。采用非线性平面应变有限元方法对土钉墙支护设计进行数值模拟。与传统的极限平衡法相比具有显著优越性。该方法将土钉与岩土介质作为1个系统研究，对十钉支护的作用机理、变形、和土钉墙内的受力进行分析，计算开挖最终阶段的变形量。与工程实例的对比检验，证实该方法的合理性。研究结论对土钉墙支护的设计与施工具有较高的应用价值。

| Abstract: | Soilnail wall support is an economical, safe, and reliable suport pattern in foundation ditch engineering. In this article non-linear FEM, which boasts many prominent advantages over traditional limiting equilibrium method, is applied to numerical simulation in soilwall support design. Regarding the soilnail and rock or soil media as an integrated system, it analyzes the mechanism of action, deformation of the soilnail supporu as well as the stress state in the soilnail wall, and calculates the deformation quanity in the final stage of excavation. Checking against practical engineering instances proves the rationality of the mathod and the conclusion drawn from the research is that it is valuable in the design and construction of soilnail wall supports. |
