| Abstract: | The mechanism and design of soil nailing suppport is in a stage of study due to its complexity. Based on the mechanism of soil nailing the constitutive relation was studied, the failure criteria, excavation load and displacement calculation FEM model and simulation process of soil nailing have been setup, the reliability of numerical calculation in soil nailing design is verified by example, test, which can provide base for soil nailing support design. |
| Keywords: | soil mailing numerical simulation test |
