FE-simulation of soil compaction

摘要

Finite Element calculations are presented, which simulate different aspects of soil compaction with vibratory rollers. A simple, one dimensional rod model is used to show the occurrence of shock waves due to dynamic loading and a hypoplastic material. A two dimensional, more sophisticated model is used to simulate passes of vibratory rollers over subsoil. The correctness of the calculated results is proven by a comparison with field measurements.
