Abstract

Reinforced soils have been widely used in geotechnical structures as a result of their satisfactory performance and cost effectiveness. A number of investigations have been carried out to find out the seismic deformation modes of reinforced soil walls with conventional horizontal inclusions. This study puts forward a new concept of soil reinforcement, applying vertical reinforcement together with conventional horizontal reinforcement. A key difference between the general practice and after insertion of vertical reinforcement is that the latter not only provides passive resistance against shearing due to making intact layers but also increases the strength and stability of the reinforced soil. The concept of soil reinforcement behaviour and its positive effects are analysed under static and seismic loads. The vertical reinforcement can be implemented by stitching horizontal reinforcing layers to each other. For this purpose, different techniques can be applied. Two practical and possible methods, proposed by the authors, are presented. Employing this technology can promote numerous benefits to the current industry of soil reinforcement.

Application of Vertical Reinforcement for Performance Enhancement of Reinforced Soil Under Seismic Loading

San Diego, California

Reinforced soils have been widely used in geotechnical structures as a result of their satisfactory performance and cost effectiveness. A number of investigations have been carried out to find out the seismic deformation modes of reinforced soil walls with conventional horizontal inclusions. This study puts forward a new concept of soil reinforcement, applying vertical reinforcement together with conventional horizontal reinforcement. A key difference between the general practice and after insertion of vertical reinforcement is that the latter not only provides passive resistance against shearing due to making intact layers but also increases the strength and stability of the reinforced soil. The concept of soil reinforcement behaviour and its positive effects are analysed under static and seismic loads. The vertical reinforcement can be implemented by stitching horizontal reinforcing layers to each other. For this purpose, different techniques can be applied. Two practical and possible methods, proposed by the authors, are presented. Employing this technology can promote numerous benefits to the current industry of soil reinforcement.
