摘　　要：简要讨论振动压路机振动压实地基的基础理论和当前国内外发展概况，探讨了土壤密实度变化对土壤－机械振动系统的动态特性的影响及其参数辨识方法。This article briefly discusses the basic theory of the foundation compacted by the vibroroller and gives a survey of its development both at home and abroad. A study has been made to the influence of the change of compactedness of the soil on its dynamic properties and to the method for its parameter identification. Experiments demonstrate that it is practical to detect the foundation compactedness in real time by measuring the change of the damping ratio of the soil.
