Notes:
Soil nailing, developed from the New Austrian Tunnelling Method, has been widely usedin many countries and regions in the world since the 1970’s. This technique is used to stabilize in situsoil mass by installing a large number of closely spaced unstressed inclusions into the soil mass toincrease its strength and stability. Since the mid 1970’s, several design methods have been proposedbased on laboratory and field tests. Among the design criteria in these methods, the pull-out resistanceof a soil nail is a key parameter that controls the stability assessment of soil nail structure. In theprevious investigations, the soil dilatancy was found to be an important factor that influences the soilnail pull-out resistance especially for drill-and-grout soil nails. In order to study the influence of soildilatancy on soil nail pull-out resistance, laboratory pull-out tests and numerical parametric studieshave been carried out for soil nails in Completely Decomposed Granite (CDG) fill. The results showthat the soil dilatancy has a significant influence on the soil nail pull-out resistance
