Three Dimensional Finite Difference (3D FD) Analysis of Soil Nailing Wall

The technique of soil nailing as a method of soil reinforcement in situ has been increasingly used to stabilize open excavations. Analyzing of the soil nailed structure by numerical models is an appropriate method for predictions of the deformation behavior of a soil nailing wall and actual mobilized forces in the nail. In this paper, 3D FD analysis was used to investigate of soil nailing wall mechanism in cohesion and granular soils under service state and limit state. The behavior is investigated to study influence of: (1) shear strength of the soil, (2) distribution of nail lengths. The results can be useful for the design of soil nailed structures.
