Abstract
The nailing method is utilized for temporary and permanent stabilization of the drilled excavations and walls. In most instances, nailing is much more cost-efficient than other excavation stabilization alternatives, hence the popularity and rapid development of nailing technology have been increased. In this research, several parameters such as changes in the height of the excavation, alterations in the soil environmental parameters, changes in the nails’ layouts, and their lengths were analyzed to evaluate the conduct of the nailing system. The findings of this study demonstrated that each of the mentioned parameters makes changes in the locations, and the forces of the system. Further examination of the impact of each parameter, the maximum and minimum impact of the changes are assessed and ultimately, a general insight is created for designing each constituent of this study.
