✦ Synopsis

The paper by W. H. Zhou and J. H. Yin includes a problem regarding the pull-out resistance of a soil nail within dilatant soils. They calculate the pull-out force due to soil dilatancy using cylindrical expansion in an elastic medium. However, the soil in the vicinity of the nail experiences significant local softening behavior. This discussion indicates another method for calculating the normal stress due to soil dilatancy.
