| 摘 要： | 根据结构振动理论，分析了振动压实机械与被压土体的相互作用机理，研究了碎石土振动压实动态监测的理论依据，建立了一套适用于加速度监测仪的振动压实动态监测数据采集系统．在大量室内试验数据的基础上，研究了振动压实过程中加速度电信号响应随碎石土密实度的变化规律，发现二者具有显著的线性相关性．研究结果为实现快速有效的碎石土路基密实度实时动态监测提供了理论依据和工程指导． |

| Abstract: | According to the theory of structure vibration and the interaction mechanism of the system constituted byvibrating compactor and gravel soils,the theoretic warranty of dynamic monitoring for vibrating compaction is stud-ied,and a data collecting system of the dynamic monitoring suited to the monitoring apparatus with acceleration trans-ducers is established.It is found from the monitoring data that the response of the acceleration transducer is linearlyrelative to the compaction degree of gravel soils.The result provides the theoretic warranty and guidance to on-linedynamic monitoring for the vibrating compaction of gravel soils quickly and effectively. |
| Keywords: | Gravel Soils vibrating compaction on-line monitoring quality control |
