With regard to Large Diameter Reinforced Anchor which is the improved Earth Reinforcment, the characteristics of the hollow FRP rods made by Vinylon for the reinforcement of soil cement colum are reported. Many merits were obserbed by hollow rod like bamboo shape compared with standard round rod or strand rod. Hollow rod dissolves the problem of the dimentional unstability for 7 strand rods, improves the tensile strength and better adhesion with concrete because of bigger surface area. Moreover, the simple end fixing of rod were realized because the end of hollow rod were divided into 6 pieces and locked by conic wedge. Regarding the durability of Vinylon FRP rod, alkaline resistance and creep raputure were measured by the standard of the Japan Society of Civil Engineers and suggesut the long durability for that.
