Artificial structural soil capable of simulating structural characteristics of natural undisturbed soil and preparation method of artificial structural soil

The invention discloses artificial structural soil capable of simulating structural characteristics of natural undisturbed soil and a preparation method of the artificial structural soil, and is characterized in that the structural soil contains a road liquid curing agent RoadyesTM, and the structural soil prepared by adopting the RoadyesTM as a cement is closer to the natural undisturbed soil in structural and mechanical properties in a relatively large water content range, so that the structural soil can be used for simulating the structural characteristics of the natural undisturbed soil. The method has more advantages; and by introducing the strain structural parameters mp, the relationship between the strain structural parameters mp of the structural soil of the three different cement and each test variable is established, the mechanical properties and structural characteristics of the artificial structural soil prepared by using the RoadyesTM as the cement are similar to those of the undisturbed soil, a
