摘要
振荡压实是８０年代中期出现的一种新的压实技术，它利用在材料中产生的快速交变剪应力使材料的颗粒重新排列而变得更加密实。本文分析了振荡轮与地面相互作用的特点以及分阶段建立动力学模型的可行性。讨论了振荡轮在土壤上工作的动力学过程和系统在频率域和时域的响应特性。
Oscillatory compaction is a new compaction technique developed from the middle eighties, which works with a succession of rapidly alternating shear stresses to make a rearrangement of material particles in a denser way. The paper analyzes the features of interaction between oscillatory roller and ground, and demonstrates the feasibility to establish dynamic model by stages in oscillatory compaction. The dynamic process of the oscillatory roller working on the soil foundation and its response characteristics in frequency and time domain are discussed.
