Abstract
The described project involved a two-lane road with many curves in a mountainous area of Tokyo. The purpose of this project was to make the road straight for overcoming the problem of heavy traffic. As one of the measures, in the year 1985, it was decided to construct a road tunnel in the hilly part. For connecting the existing road at one exit of the new tunnel, the road had to be widened by cutting the slope. The cutting slope was stabilized by soil nailing, which was a combination of rebar with 80–100 mm diameter and cast-in-place mortar placed in the drilling hole.
