Soil nail head is an essential feature of soil nails which help prevent active zone failure. Active zone failure involves shallow failure in the outer part of slope within active zone and it fails by separating and sliding down the slopes and sols nails remain in place.

Soils nail heads also enhances the mobilization of tensile resistance of soil nails and increases the factor of safety of slopes.


This question is taken from book named – A Self Learning Manual – Mastering Different Fields of Civil Engineering Works (VC-Q-A-Method) by Vincent T. H. CHU.
