In order to investigate the dynamic properties of jute fiber reinforced loess, the natural jute fiber with low price and good performance was added into the loess according to certain mass mixing ratio. The dynamic stress-strain relationship, dynamic modulus of elasticity, damping ratio and other indicators were tested to analyze the dynamic properties of loess with different mass ratios of jute fiber and to study the reinforcement mechanism. The test results show that the dynamic stress increases first and then decreases with the increase of jute fiber content. Under the same strain condition, the dynamic stress reaches the maximum when jute fiber mass ratio reaches 0.3%. The dynamic modulus of elasticity of loess with different jute fiber mass ratios is greater than that of normal loess and decreases with the increase of dynamic strain. The damping ratio effectively reduces by incorporating a certain mass of jute fiber, and the average values of maximum damping ratio decrease compared to minimum damping ratio at different surrounding pressures (100 kPa, 200 kPa, 300 kPa) are 91%, 120%, 100%, respectively. SEM images indicate that the incorporation of excessive fiber causes the fibers to be entangled with each other, resulting in the decrease of dynamic properties and other indicators.
