TESTING STUDY ON CRATER FORMED BY EXPLOSION AND PROPAGATION LAWS OF GROUND SHOCK IN LIMESTONE
|
Abstract:
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.
