|Abstract:||A series of simplified failure modes has been used in this paper to describe the behaviour of soil-nail lateral interaction. The criteria for determination of the possible failure modes for a soil-nail structure are set out on the basis of the relative stiffness and strengths of the soil and nail and the local relative lateral displacement across the shear zone. This local relative displacement is produced along a potential sliding surface of the reinforced soil-nail retaining structure. Expressions for calculation of soil-nail lateral resistance have been derived for each potential failure mode. It is found that soil-nail lateral resistance is dependent not only on the relative stiffness and yield strengths of the soil and nail but also on the local relative lateral displacement across the shear zone. Good agreement among the results of numerical simulation of soil-nail lateral performance, published experimental data and theoretical predictions have been demonstrated, to support the validity of the proposed approach for estimating soil-nail lateral resistance capacity in soil-nailing design.|
