As a new type of material, Glass Fiber Polymer-Soil nailing (GFP-SN) can replace the steel to be applied in the slope support, excavation support and other civil engineering.
GFP-SN is a new kind of material formed with resin and glass fiber compound.
Light weight, high strength, corrosion resistance, electrical conductivity and so on, all are properties of GFP-SN, which mean that steel can be replaced by GFP-SN as new material to reinforced soil nailing[1].
Currently, GFP-SN, as a new type of composite material, has drawn more and more attention from researchers.
