Abstract
The Soil-nailing installed to the slope or the vertical excavation surface shows reinforce effect using frictional resistance between ground and grout. This friction is showed the more the shape of grout is rough, the more efficient.. This study is about the characteristic behavior of Soil-nailing has partial extension grout made artificially control. In this study, we refer to the new boring machine that can make partially extended grout and perform 3D analysis between of the partial extended grout and the general grout of a cylinder shape using the finite element method for comparing.
