Discrete Simulation of Vibratory Roller Compaction of Field Rockfills

Vibratory roller compaction is a well-known method in improving the mechanical properties of field rockfills. However, meso mechanism rockfill densification under vibratory has not been understood clearly. This paper presents discrete numerical to simulate Firstly, particles were modeled by irregular and stochastic clusters, which can be breakable. In addition, segregation rockfills was replicated practical manner. Then, new model presented, frame inertia considered. Finally, developed applied Shui Buya Project. Results show that (1) simulations agree well with experiments; thus, feasibility rationality simulation are verified; (2) dynamic response predicted presented calibrated parameters; (3) considered much more accurate than models early studies. Thus, further adopted explore future.
