| 摘 要： | 采用考虑转动自由度的修正古德曼节理单元作为接触面单元,将平面弯曲钢钉单元和考虑弹塑性的土体单元相互连接,利用有限元方法对土钉支护的作用机理、变形及其受力进行分析,并将其用于工程设计中。与实际监测结果的对比验证可知,该模型是有效的和可行的,研究结论对土钉支护的设计与施工具有较高的应用价值。

| Abstract: | The mechanism of action,deformation and stress state of soil nailing were analyzed using the finite element method.In the finite element model,the modified Goodman Jointed Element was adopted to simulate the interface between the steel nail bent in plane and the elastic-plastic deformed soil body.The model then was applied in an engineering design.Comparison with monitoring results and inspections in engineering practice shows that the soil nailing model is quite effective and feasible.The model may find wide application for design and construction in soil nailing engineering. |
