ABSTRACT
Soil nail system has been around over about thirty years as earth-retaining structure. The structure solves problem associated with slope failure during slope cutting, disturbed terrain and excavation. The basic concept of soil nailing can be defined as inserting a passive inclusion into the soil in a closely spaced pattern to increase the overall shear strength of the in-situ soil and restraint its displacement. This system fundamentally improves the stability, in a soil slope for example, principally through the mobilization of tension developed in the soil nails. Generally, the basic design concept of soil nailing system is still based on the conventional deterministic approaches which depends upon the transfer of resisting tensile forces generated in the inclusions into the ground through friction at its interfaces.
