【摘要】 为了研究声波探雷机理,设计了一个基于声-地震耦合原理的室内声波探雷实验系统.首先,简述声波探雷技术的基本原理;然后,详细介绍室内声波探雷实验系统的硬件组成及实验方案;最后,用一种反坦克塑料教练地雷进行实验,重点讨论实验系统的可重复性.实验结果显示,在相同实验条件下,测得的3条地表振动曲线基本重合,表明所设计的实验系统的可重复性良好,满足测试要求,可用于实验室条件下声波探雷机理的研究.更多还原

【Abstract】 In order to investigate the mechanism of acoustic landmines detection,an acoustic-to-seismic coupling based lab-scale experimental system for mines detection was developed.Firstly,the principle of acoustic mines de-tection technology was reviewed.Then the equipment and experimental design of the proposed system were described in detail.Finally,experiments were conducted with an antitank plastic coach mine and the system’s repeatability was especially discussed.Experimental results show that the three measured curves of surface vibration appear identical under the same experimental conditions,which proves that the system has good repeatability and meets the test requirements,and can be used to further lab-scale study of the acoustic landmines detection mechanism.更多还原
