Numerical Simulation of Rolling Compaction Process for Rockfill Dam by Particle Flow Code

Abstract:

Based on field compaction test of Nuozhadu I district rockfill engineering, numerical simulation was conducted to study the rolling compaction (RC) process using Particle Flow Code (PFC). Effects of different particle content to the quality of dam filling were discussed based on both numerical and filed test results. Numerical results also revealed the particle movement of the rockfill, the density of the formation mechanism and compaction characteristics during the RC process. Field test and simulated results both indicated that the RC process can be divided into three stages of vibration compaction, void filling and the unloading rebound phase
