The study also used photogrammetry to establish a high resolution 3D model and constructed a discrete element method to simulate the process of the rockfall movement and assessment effectiveness of the rockfall barrier. Numerical parameters calibrated with physical modeling are used to investigate the coefficient of restitution. Then, the numerical simulation method is further applied to the field in a full-scale case study. Finally, the results can serve as a reference for rockfall disaster prevention and associated renovation project planning.
