Theory and Design-Construction Method for Stabilization of Deep Excavation with Blast-Enlarged Soil Anchor

This paper deals with the stabilization measures with "Blast-Enlarged Soil Anchor" which has been used to stabililze a 13m depth vertical soil slope. Through FEM analysis, measurement of stress-strain of the soil anchor, and monitoring the slope displacement, it has been verified that the new slope stabilization method is of high reliability and feasibility.
