细粒散料的工程处理随应用目的不同 ,往往需要将其松散或密实 ,常用的手段是对散料施加振动作用 .本研究根据稳定状态理论与临界孔隙比 (ecr)对细粒散料的振动松散与密实机理进行了实验分析和研究 .研究结果表明 ,稳定状态理论与临界孔隙比法在判断散料振动松散与密实效应方面有很好的指导作用 ,散料质点的振动图形能可靠地反映散料是否达到稳定状态和临界孔隙比的情况 ,并为改变施工工艺参数提供参考依据 The engineering treatment of fine particle bulk materials often needs to be loose or dense depending on the application purpose, and the common method is to apply vibration to the bulk materials.In this study, based on the theory of steady state and the critical void ratio (ecr) Vibration looseness and compact mechanism.The experimental results show that the steady-state theory and critical void ratio method have a good guidance in judging loose vibration and dense effect of bulk material, the vibration pattern of bulk material particles can be reliably Reflects the bulk material reached a steady state and the critical porosity ratio of the situation, and to provide reference for changing the construction process parameters
