Method for artificially preparing structural soil

The invention aims to provide a novel method for artificially preparing structural soil, which can better simulate natural undisturbed soil in a relatively large water content range. An indoor direct shear test is adopted, the concept of structural strength is introduced, the content of cement with the structural strength similar to that of natural undisturbed soil is determined by adding different contents of road liquid curing agents (RoadyesTM) to prepare the structural soil, and the structural soil with cement and lime as the cement is used as a contrast test. Based on a lateral confinement compression test, the influence of different cement and water content on the compression deformation characteristic of artificially prepared structural soil is compared, a strain structural parameter mp is introduced, and the relationship between the mp of the structural soil of three different cement and each test variable is established; the structural soil prepared by using the RoadyesTM as the cement is found to ha
