| 中文摘要:与地表振动钻进相比，在海底振动钻进过程中，存在海水的阻尼及海水参与振动等问题。采用简化的力学模型并用修正系数考虑了海底振动钻进的特殊工况，对影响振动钻进效果的振动器振动参数进行了全面分析，并设计了一种适合于在水深500 m以浅的海底土层进行振动取样钻进的振动器。 |

| Abstract:Compared to the vibrating sampling on the ground, there are problems of seawater damping and seawater vibrating during seabed vibrating drilling. Simplified mechanical model and modified coefficients were taken into account of the specific conditions in the seabed, the effects on vibrating penetration by various vibrating parameters of seabed vibrating sampler had been discussed in this paper. A seabed vibrating sampler suitable for seabed soil at 500 m depth had been designed according to the design theory discussed in this paper. |
