Study of Slope Stability using Flexible Facing

An experiment was conducted to evaluate the load-bearing capacity of a soil nailing system that consisted of four ۱۰mm nails and four ۱۲mm nails, reinforced in a slope with three different flexible facing materials: geo-composite facing, aluminium facing, and galvanized iron facing. The nails were spaced ۲۰۰mm apart horizontally and vertically from centre to centre. The results of the stress-strain test showed that the geo-composite and galvanized iron facings with ۱۲mm diameter nails exhibited high strength of ۰.۲۵N/mm۲ with less displacement. The relationship between stress, displacement, and the type of nails used with identical facing was examined. The stability of the slope was also analysed to investigate the impact of nail parameters and type of facing on displacement under varying loading conditions.
