The TEXSOL reinforcement mechanism was analyzed theoretically. The influencing rule of several factors on TEXSOL reinforcement character was researched; and the defect of the existing experimental calculating formula of TEXSOL strength was analyzed. Based on a lot of experimental results

a series of empirical coefficients were determined. The relationship of influencing factors and TEXSOL reinforcement character was gained. The research shows that the increment of TEXSOL cohesive strength is related to the fiber toughness

fiber fineness and TEXSOL mixing ratio. The empirical formula of TEXSOL reinforcement was proposed. Finally

the straight-wall height method was extended to the design of TEXSOL retaining wall; and the proposed empirical formula was used to analyze the internal stabilization of TEXSOL retaining wall.
