Neoweb cellular confinement in reinforced slopes stability

Abstract

Neoweb reinforced soil may be used in many areas of geotechnical engineering, however, there is little information on analysis of the behavior of neoweb reinforced slopes. Due to the height of the neoweb, the neoweb-reinforced mattress more likely provides a beam or plate effect than a planar membrane effect. The purpose of this paper is to use beam model to simulate the neoweb behavior as a flexible slab foundation which can carry both bending and membrane stresses for stability analysis of neoweb reinforced slopes. In addition, the interface resistance between the neoweb-soil was considered. The Young’s modulus of neoweb encased soil was obtained from the elastic modulus of the unreinforced soil and the tensile modulus of the neoweb reinforcement using an empirical equation.
