中文简介
机械基础的设计需要在感兴趣的频率下预测地基系统的动力响应。响应通常根据一些参数进行量化，这些参数包括位移、动态刚度、共振频率、共振频率和固有频率下的振幅。本研究的目的是调查垂直动态响应的嵌入式基础实验。结果表明，埋置增加了地基系统的刚度、阻尼和固有频率，减小了位移和共振幅值，但埋置对共振频率影响不大。
英文简介
Design of machine foundations requires the prediction of the dynamic response of the foundation system at the frequencies of interest. The response is typically quantified in terms of a number of parameters that include the displacement, the dynamic stiffness, the resonant frequency, the amplitude at the resonant frequency and the natural frequency. The objective of this study was to investigate the vertical dynamic response of an embedded foundation experimentally. It was found that embedment increases the stiffness, damping and natural frequency of a foundation system, reduces the displacement and resonant amplitude, but that embedment has very little effect on the resonant frequency.
