1879 As shown in Figure 5.1, the steel anchor system achieves a global Factor of Safety (F.S.) of 1.6, with the anchors effectively intersecting the critical slip surface and stabilizing the potential failure mass. The required cross-sectional area for the steel tendon is 106 mm², and the calculated bond length results in :K ≥3.7 ï, satisfying the regulatory minimum requirement of :K ≥3.0 ï. In contrast, the graphene-reinforced GFRP system requires a reduced tendon cross-sectional area of 73 mm² (approximately 31% lower than steel), while maintaining a similar bond length requirement of :K ≥ 3.8 ï. As will be observed in Figure 5.2, the overall stabilization mechanism remains comparable, with the anchors effectively controlling the potential slip surface despite the slightly lower global F.S. of 1.5. Figure 5.2: Graphene-Reinforced GFRP Anchor System – Slope Stability Analysis. The following table (Table 5.2) summarizes and compares the results obtained for both alternatives.
