Abstract

By conducting unconfined compression strength tests, the influence of polypropylene fiber, glass fiber, basalt fiber, and carbon fiber on the mechanical properties of lime soil was studied to determine the fiber with the best modification effect on lime soil (lime mixing content of 6%, fiber content of 0, 0.5%, 0.75%, and 1% respectively). Research shows that all the four types of fiber can improve the modulus-strength ratio of lime soil. Specifically, polypropylene fiber can significantly reduce the brittleness index and improve the toughness index of lime soil, while the other three types of fiber have the opposite effect. Additionally, except for polypropylene fiber, the other three types of fiber do not significantly improve the various properties of lime soil, which is mainly because polypropylene fiber has sound dispersibility in soil, while the other three types of fiber have poor dispersibility and are prone to clumping, greatly affecting the interfacial friction and spatial confinement effect between fiber and soil particles.
