Investigation on the dynamic shear modulus of fiber-reinforced sand

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract As a new type of composite material, fiber-reinforced soil has attracted much attention due to its good dispersibility, mechanical properties and durability. Based on the dynamic triaxial test, the dynamic characteristics of polypropylene fiber-reinforced sand were studied, and the effects of fiber content (w), fiber length (lf
