SpletIn the previous research, slope improvement analysis using soil nailing with 27 variations modeling. Figure 1 shows slope reinforcement analysis with Slope/W 2007 program [1]. Slope reinforcement analysis with soil nailing was used for consideration of consider of implementation, minim al environmental pollution, and soil parameters can be used. Splet04. jan. 2024 · The total thickness of shotcrete is usually kept in the range of 50–200 mm. It is applied in layers, each layer having a thickness in the range of 25–40 mm. The layer thickness in excess of 40 mm requires special mix design to minimise rebound losses. the 31st president of the us
