自本世纪二十年代德国土力学会提出动力基础有部分参振土质量的概念以来,国内外不少专家们引用这一概念,但很少有试验验证动力桩基础是否存在参振土质量。因此,这是一个有待于进一步研究的问题。有文献〔2〕、〔3〕表明:桩基础振动系统采用质量-阻尼-弹簧的计算模式时,部分参振土体和部分桩体被假定为振动体系同相位的质量。然而,这种假定未能经过大量 Since Germany’s soil mechanics conference in the 1920s proposed that there are some aspects of the concept of vibrating soil quality on the basis of power, many experts at home and abroad have quoted this concept, but few tests have verified the existence of vibrating soil quality for power-pile foundations. Therefore, this is a question that needs further study. Some literatures [2] and [3] show that when the pile foundation vibration system adopts the mass-damper-spring calculation model, some of the vibrating soil bodies and some of the pile bodies are assumed to have the same phase quality as the vibration system. However, this assumption did not go through a lot
