| 摘 要： | 结合检波器与松散地表耦合的实际,设计了双自由度耦合模型,从理论上分析了检波器与地表耦合系统的特性,并结合野外实验定性地分析了在不同表土情况下,检波器尾锥与地表耦合系统中尾锥与地表之间的阻尼变化时对耦合系统特性及地震资料的影响,揭示了合理的选择检波器尾锥与地表之间的阻尼在地震信号采集中的意义。

| Abstract: | This paper designs the double scale coupling model considering the actual condition of the geophones coupling with the loose soil,and analyzes the characteristics of the geophone ground coupling system in theory.This paper also qualitatively analyzes the effects to the seismic data and the coupling system's characteristics that generated by changing the damping between the spike and the ground in the geophone spike and ground coupling system under the different ground soil condition.At last this paper points out the meaning of choosing the damping between the geophone spike and the ground properly in seismic data acquisition. |
