The interfacial mechanical interaction between fibers and soils is the key factor controlling the engineering properties of fiber-reinforced soils.In order to improve thee mechanical properties of fiber-soil interface,a new wave-shape fiber is developed as a reinforcement material.An innovative pullout test device is designed.By applying this device,a series of single fiber pullout tests are carried out on fiber-reinforced soil samples.The pullout characteristics and interfacial shear strength of wave-shape...
