Abstract

The anchorage in the form of soil nailing can be used for stabilizing weak natural soil slopes. It can also be used for
steepening of new or naturally existing soil slopes. The nail anchorage in the soil can be in the form of
reinforcement and in the different materials with different cross section area. The most of the failure of nail in soil
have been reported as pullout failure due to tension on the nail, particularly in sandy soil. Because of increased cost
and safety concerned the field test to determine pullout force is difficult. Therefore the laboratory studies were
carried out in simulated conditions. In this research work, the laboratory investigation were carried out to observe
the effect of tensile (pullout force) force on the soil nail in sandy soil. The pullout force on the nail was gradually
increased and the corresponding displacement was recorded till failure of the nail due to continues sliding. The test
results were compared to Standard values in earlier studies. It has been shown that a simple loading frame with
testing tank model can be used to simulate the pullout load–displacement relationship and to determine peak
pullout force of different type of nails. The various parameters studied were embedded length of the nail, the type of
surface, the material and cross-section of nail.
