Research on the Application of FRP Composite Materials in Subgrade Slope Protection and Drainage Facility
FRP composite materials are composed of fiberglass and unsaturated resin,which are widely used in construction and transportation fields due to their advantages of light weight,high strength and corrosion resistance.The material is usually used to make subgrade slope protection and drainage facilities,such as chute,curb,arch skeleton,etc.The research and development of FRP composite materials can effectively improve the stability and safety of slope engineering.Based on Anyang-Luoshan Expressway in Henan Province,this paper introduces the composition,preparation and properties of FRP composite material,and analyzes its application effect in subgrade slope prevention and drainage facilities through examples.The results show that the FRP composite material has good economy and engineering feasibility in subgrade slope engineering.
