Effect of wall batter angle on soil nail walls performance

Soil nailing is a very versatile excavation retaining system for deep excavations in urban areas surrounded by major structures and infrastructures. Using Battered face for soil nail wall system can increase global stability of the system and decrease lateral deformations of the walls. But, high cost of lands in cities caused to more applications of vertical walls. In this study we have surveyed the effects of variation of batter angle of the soil nail wall face on stability and lateral deformation of the wall. Some Finite Element and Limit Equilibrium models were developed to analyze performance of the walls. The analyses results present the variation's rate of the wall stability and lateral deformation of the wall by the wall batter angle increment. These results can be used to investigate the benefit to cost of using wall batter angle in soil nail walls projects.
