摘要
在描述夯锤对夯点土体的动力作用的基础上,阐明了夯锤自一定高度下落到与地面接触时开始的减速运动过程中的一系列动力过程和效应,阐述了强夯振动传播和衰减规律,系统介绍了强夯振动频域分析的理论,建立了夯点锤土复合体的振动模型,分析了夯点土体振动特征与夯点土体加固状态之间的物理联系,实现了地基强夯加固状态的实时振动监控
In the paper,dynamic effect of tamping hammer power effect on tamped soil is described.On the basis,a series of power process and effect in the deceleration movement process of tamping hammer from certain height to the ground are described,and dynamic compaction vibration transmission and attenuation rules are described.Theory of dynamic compaction vibration frequency domain analysis is systematically described,vibration model of hammer soil complex on the compaction point is established,and physical contact between compaction point soil vibration features and compaction point soil consolidation state is analyzed.Real-time vibration monitoring of ground foundation dynamic compaction consolidation state is realized.
