MJ Turner, director, Applied Geotechnical Engineering. This paper was first published in GE’s November 1999 edition.

Summary

This paper summarises the results of a full-scale trial soil nail wall reinforced with the PermaNail system. The trial wall was constructed in a slightly cohesive granular fill and was eventually 6.5m high, with a face angle of 20 to the vertical. After six months, and a surcharge load of 105t (equivalent to a surcharge pressure of 32.9kPa). The maximum recorded horizontal movement of the face was 3.5mm.
