Abstract Geopolymer solidified soil is an innovative waste reuse method in the engineering field. Addressing the issue that dynamic loads such as earthquakes and vehicle traffic can easily cause damage to subgrade soils, this work explored the use of blast furnace slag and fly ash as geopolymer binders to solidify soils from the Zhangjiakou region. A staged loading dynamic triaxial test method was employed to investigate the effects of binder content, initial deviatoric stress, confining pressure, and curing age on the dynamic deformation characteristics of geopolymer solidified soils. The dynamic backbone curve and dynamic elastic modulus of the solidified soil were analyzed, and a dynamic constitutive model for geopolymer solidified soil was fitted. The results indicate that under staged cyclic loading, the dynamic backbone curve and dynamic elastic modulus exhibit nonlinear behavior. As the binder content, initial deviatoric stress, confining pressure, and curing age increase, the dynamic backbone curve becomes steeper, and the dynamic elastic modulus increases, thereby enhancing the structural stability and resistance to dynamic deformation. Based on the Hardin-Drnevich model, a modified coefficient k is introduced, leading to a modified Hardin-Drnevich model that can reflect the effects of initial deviatoric stress, binder content, confining pressure, and curing age. These findings provide a theoretical basis for the practical application of geopolymer solidified soil in engineering projects.
