ON THE NAILED SOIL SLOPES RESEARCH DEVELOPMENT

Abstract

The slope stability was researched over the past decades, understandings the behavior of
nailed soil slopes, with their properties and characteristics, have guided to development of enhanced
recognizing of the variation in nailed soil slopes parameters. Failures can arise over time, hence the
identification of the necessities and the restrictions of laboratory and in situ testing for evaluating nailing
parameter have to be deeply understood. Many researcher have enriched and refined the knowledges of the
principles of soil nailing mechanics that associate soil behavior to slope stability and factor of safety. This
paper is aimed to explore some of important state of the art development of nailed soil slope and analytical
techniques extended by extensive investigation of the mechanics of slope stability analyses. The most
significant effective parameter that play important role in slope safety factor in almost of many works are
length, nailing angle, and distance between center to center of nails. Slope angle, connection of nailed head,
the distance with toe and nail diameter were also the points that cannot be neglected in their study. Choosing
the proper cable or pile element in the finite element modeling and the mobilized both axial and shear forces
are also reviewed in this paper.
