Abstract: As a new geocomposite, glass fiber cement soil has better mechanical properties for the reinforcement effect of glass fiber, and it can be widely used in such projects as subgrade replacement, subgrade strengthening, slope protection, foundation cushion, etc. However, the mechanical properties of glass fiber cement soil with different glass fiber contents under different confining pressures still need further research. In this paper, glass fiber cement soil with different ages and glass fiber contents were researched through laboratory triaxial shear test under different confining pressures. Based on the laboratory test results, the strength and deformation properties of glass fiber cement soil and the rational mixing ratio of glass fiber were analyzed. It was found that confining pressure and glass fiber content played important roles in affecting the stress-strain behavior of glass fiber cement soil samples at the same age. This research is helpful for wider application of glass fiber cement soil.
