The most important principles in deep excavation retaining structures are design and monitoring of the excavation wall displacement values. One of the best and most widely used methods of stabilizing the walls is using the anchorage and nailing systems. Shift in the excavation pit wall is very important because it can cause damage to adjacent buildings. To examine the effect of various approaches for simulation, northern wall with finite element software, Plaxis and Geoslope, was built using the methods of anchorage and nailing for examining the soil behavior and structural elements. Mohr-Coulomb is the most common constitutive model in numerical modeling with some weaknesses such as unrealistic heave of the excavation bottom and thus variations in the displacement field.
