本文根据大量的强夯地面振动监测资料对强夯地面振动的衰减规律进行了统计分析 ,分析表明用夯检距的负幂函数描述强夯地面振动衰减统计规律是合理的。量纲分析证明 ,上述统计衰减规律也是符合物理规律的。谱分析表明 ,各个单频成分的强夯振动衰减同样符合负指数函数规律 ,衰减指数在频率域中的变化规律可用频率的三次多项式表示。 According to a large number of data of ground compaction monitoring, the attenuation law of ground compaction by dynamic compaction is statistically analyzed. The analysis shows that it is reasonable to describe the statistical rule of ground compaction by negative power function of rammer. Dimensional analysis shows that the statistical attenuation law is in line with the laws of physics. The spectral analysis shows that the vibration attenuation of the dynamic compaction of each single-frequency component also accords with the law of negative exponential function. The variation law of attenuation index in the frequency domain can be represented by the cubic polynomial of frequency.
