Abstract: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 geophone-ground coupling effects. Through the coupling natural frequency factor and the coupling damping ratio factor, quantitative analysis of geophone-ground coupling effects is realized. Based on QT program, a quantitative analysis software is developed. The feasibility and effectiveness of the proposed quantitative analysis method is verified by coupling effect test, and the practicability and stability of the quantitative analysis software is also confirmed by field application test.
