With today's society increasingly paying attention to sustainable development, the field of geotechnical engineering is also actively seeking environmentally friendly solutions. Among them, the application of glass fiber reinforced plastic (GFRP) rock bolts is gradually becoming an important direction in sustainable geotechnical engineering. GFRP rock bolts is a composite material composed of glass fiber and resin. Compared with traditional metal boltss, it has significant environmental advantages. First, fiberglass is a recyclable material whose production process uses relatively low energy and has a smaller environmental impact than metal mining and processing. This enables GFRP rock boltss to have less environmental impact during their life cycle and meets the requirements of sustainable development. Secondly, GFRP rock bolts have good corrosion resistance. Compared to metal bolts, GFRP rock bolts are less susceptible to corrosion and therefore have a longer service life in wet or corrosive environments. This not only reduces the frequency of material replacement, but also reduces the demand for resources, which is in line with the principle of sustainable resource utilization. In addition, the lightweight characteristics of GFRP rock bolts are also one of its environmental advantages. Compared with traditional metal boltss, high strength GFRP rock bolts have a lower density, which reduces energy consumption during transportation and construction. Lightweighting not only helps reduce energy consumption on the construction site, but also reduces carbon emissions during transportation, which is beneficial to mitigating the impact of climate change. Finally, the design and manufacturing process of GFRP rock bolts is relatively flexible and can better adapt to various geotechnical engineering needs. This flexibility enables engineers to plan and design more efficiently, reduce resource waste, and improve project efficiency. GFRP rock boltss in sustainable geotechnical engineering have injected new impetus into the sustainable development of the engineering field through their environmental protection advantages. With the continuous improvement of environmental protection requirements, GFRP rock boltss are expected to be more widely used in geotechnical engineering, providing a feasible technical approach to building a more environmentally friendly and sustainable future.
