Creep pullout mechanical behaviour of V-Armed Hybrid Anchor soil nail in slope stabilisation / Mohammad Ashari Muda

Various slope stabilisation and landslide protection methods are available to combat and slide risk. Soil nailing is a soil reinforcement technique or mechanical technique that provides internal stability to reinforce the slope post construction and during excavation. It is widely implemented due to the simplicity of construction and it is economical. However, there are shortcomings in the system based on many failures reported by the authorities. One of the shortcomings in the conventional soil nails is the creep behaviour in the pullout resistance force i.e., the pre-stressed tension diminishes when slippage between the nails and the surrounding soil occurs. Creep occurs when the nail is pre-stressed; it elongates and is followed by longitudinal movement towards the bearing plate thus lead to the loss of tension. This research focused on the bond resistance, shape and failure mechanism of the V-Arm Hybrid Anchor due to creep effect.
