1878 Table 5.1: Summary and Comparative Table of the Main Properties of Both Options. COMPARISON Graphene-Reinforced Glass Fiber Profiles (GFRP) Steel Corrosion Resistance High resistance to chemical agents Prone to oxidation and corrosion Density 1.83 g/cm³ 7.85 g/cm³ Electrical and Thermal Conductivity Non-electrical conductor. Low thermal conductivity Electrical and thermal conductor Strength High strength-to-weight ratio Higher weight for equivalent strength Impact Resistance Non-deformable. Glass fiber fabric distributes impact loads Possible deformation under impact loading Wave Transparency Transparent to EMI/RFI transmissions Interferes with EMI/RFI transmissions Installation Lightweight for lifting and installation Requires specialized installation equipment Cost Low maintenance and installation cost Low initial cost. Higher long-term maintenance cost compared to GFRP Color and Finish Pigments can be added, allowing a wide range of colors Steel must be painted to achieve color finish The Factors of Safety (F.S.) of both systems do not differ significantly. The upper representation corresponds to the steel anchor system with an F.S. of 1.6, while the lower representation corresponds to the graphene anchor system with an F.S. of 1.5. Figure 5.1 presents the slope stability analysis schemes for both proposed configurations. Figure 5.1: Steel Anchor System – Slope Stability Analysis
