Three-dimensional centrifuge modeling of soil nail walls
Assuming plane strain deformation instead of three-dimensional behaviour of nailed convex trenches in the design process might lead to life and property losses during the operation period. In this research, the behaviour of convex nailed trenches was investigated. Various physical models with three-dimensional and plane strain conditions were tested using a geotechnical centrifuge. The failure acceleration was measured as well as the walls deformations. Results showed that convex nailed trenches had less stability than long nailed trenches. It was also revealed that the connection quality of the trench sides at their intersection had a significant effect on increasing stability. Finally, a method was proposed to increase the stability of the convex trench in which the two sides of the trench are sewed together by a series of diagonal nails. Using this method to reinforce the model resulted in the maximum stability and minimum deformation of the convex trench.
