摘要
简介了本课题研究的国内外现状,介绍了试验背景和试验方案,给出了石灰岩中爆炸成坑结果以及应力和加速度的实测波形,并对测试结果进行了分析,得到了石灰岩中爆炸成坑经验公式以及地冲击传播规律,结果给出现场石灰岩中应力波的传播速度大约为3500m/s。
The current state in the field of explosion crater and induced ground movement is reviewed. The testing background and plan are introduced. The radius of crater formed by explosion and the recorded waveform of stress and acceleration are gained in the site of limestone. The recorded results are interpreted,and the experience formula of crater formed by explosion and the propagation laws of ground shock in limestone are obtained. The velocity of stress waves propagation is about 3 500 m/s in the site.
