| 摘 要： | 设计一个声波激发的地表振动检测系统,用基于Labview的软件平台实现数据的采集与处理。用扬声器发出扫频的正弦声波激励地表产生地表振动,并用地震检波器接收地表振动速度信号,通过NI 5112数字化仪传送到计算机,在Labview环境下进行滤波、频谱分析、波形显示与数据存储等处理。实验结果显示,该系统能有效完成测量任务,可用于声-地震耦合现象的进一步研究。 |

| Abstract: | An experimental system for acoustic-to-seismic coupling is developed. Labview software development plat- form is used to conduct data acquisition and processing. Seismic waves are induced by using a loudspeaker to generate a swept sine tone to the ground surface. The vibration velocity of the ground surface is received by a geophone, and sent to a computer via NI-5112 digitizer. Functions of filtering, spectrum analysis, waveform display and data storage are per- formed with Labview. The results indicate that the presented system can realize the test efficiently and can be used for further experimental study of acoustic-to-seismic coupling. |
