Double yield model correction flow chart. The images show the overall process of strain softening the model and a model with dimensions of 1m x 1m x 1m was created in FLAC3D for calibration, with constraints imposed on the displacements at the bottom and around the model. In addition, a vertical load of 10-5/step was applied at the top. The trial-and-error method was used to continuously correct the model parameters.
