摘　　要：针对振动压路机的振动特性、土的压实和振动在土中的传播三类问题,建立三维有限元模型进行机—土动力相互作用分析。详述了建模中的若干问题,讨论了压路机的振动特性、土的应力分布和振动在土中的传播范围。For three categories of problems concerning the vibration behaviours of vibratory rollers, the compaction of soil and the propagation of vibration in soil, the three dimensional finite element model is established to perform the analysis of Dynamic Machine-Soil Interaction of vibratory rollers. Some prob- lems concerning the model are described in details. The vibration characteristic of vibratory roller, the stress distribution in soil and the propagating range of vibration in soil are discussed.
