Abstract:

Soil nail walls are a widely used technology for retaining vertical and nearly vertical cuts in soil. A ; significant portion of the cost of soil nail wall construction is related to the construction of a reinforced ; concrete face. The potential for use of a flexible facing design for soil nail walls to replace reinforced ; concrete facing was evaluated using three-dimensional finite difference modeling and physical testing of a ; 1.5 meter by 1.5 meter unit cell of a soil nail wall in clay. A steel mesh form of flexible facing was used as a ; substitute for concrete. The finite difference model predicted large vertical and horizontal deformations for ; surcharges of approximately 5 psi. In the physical testing, the flexible facing products performed well with ; regard to strength, but the facing experienced large vertical and horizontal deformations that were consistent ; with the numerical modeling. Based on these results, it is recommended that use of flexible facing as a ; substitute for reinforced concrete be limited to non-critical structures where large vertical and horizontal ; deformations are acceptable.
