| 摘 要： | 在室内试验的基础上,提出了土密实度瞬态振动测试信号的信息熵分析方法以及时域和频域信息熵谱的计算方法,并给出了用信息熵对土密实度进行定量分析的半经验模型(拟合公式)。对信息熵的分析结果表明:在含水量一致的情况下,随着试样的干密度的增大,信号的主峰频率呈增大的趋势;在干密度基本一致的情况下,随着试样含水量的增大,信号的主峰频率呈减小的趋势,证明了将信号的信息熵作为土密实度的特征参量是合适的。

| Abstract: | Based on laboratory test,by the analysis of measuring signal,the information entropy analysis and its calculating method in time domain and frequency domain is put forward.The relationship between soil compactness and feature parameters is then investigated and the corresponding half-experiential formulas are established.Analysis result shows that the information entropy is suitable as the feature parameters of instant vibration for soil compactness |
