Considering the limited research on the dynamic properties of silty soil treated with biological enzymes, this study aimed to investigate the effects of enzyme content, confining pressure, and loading frequency on the dynamic properties of bio-enzyme-modified silty soil. Nonlinear equations were established for the dynamic elastic modulus, damping ratio, and dynamic strain of the enzyme-improved silty soil through a series of dynamic triaxial tests conducted under fractional loading. The results demonstrate an approximately hyperbolic shape in ...
