“In the field of soil nail wall structure research, experts have conducted in-depth studies on the nail head anchoring performance of prefabricated flexible surface layer GFRP reinforced soil nail walls through indoor experiments and three-dimensional numerical simulations. The research results show that the ultimate bearing capacity of GFRP reinforcement nail head is between 240~290 kN, and the stress of the thread pair is mainly concentrated in the first ring thread of the nail head. The relationship between the ultimate shear strength and the ultimate load of the nail head is clear. The safety factor of GFRP reinforcement nail head was determined to be between 1.8 and 2.0 through experiments, providing important reference for the design of soil nail wall structures.”
