Effect of wall batter angle on soil nail walls performance

摘要

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