摘　　要：针对检波器与大地耦合响应对地震数据的影响,设计了检波器与大地耦合响应的测定装置和定量分析方法:利用单自由度有阻尼的自由振动系统,定量描述检波器与大地耦合响应过程;通过等效固有频率和等效阻尼比两个参数,实现检波器与大地耦合响应的定量分析;基于QT编程语言,研发了地震检波器耦合响应定量分析软件。检波器耦合试验数据分析结果验证了该定量分析方法的可行性;将集成的定量分析软件应用于现场试验,进一步证实了该方法的实用性和软件的稳定性。Based on geophone-ground coupling effects on seismic data,we design a measure device and a quantitative analysis method for these effects.A free vibration system with single freedom degree and damping analyzes quantitatively geophoneground coupling effects. Through the coupling natural frequency factor and the coupling damping ratio factor,quantitative analysis of geophoneground coupling effects is realized.Based on QT program,aquantitative analysis software is developed.The feasibility and effectiveness of the proposed quantitative analysis method is verified bycoupling effect test,and the practicability and stability of the quantitative analysis software is also confirmed by field application test.
