VIBRATION TESTING ANALYSIS OF CHAMBER & DEEP-HOLE PRE-SPLITTING BLASTING IN TAI-CHANG FREEWAY
Zhenyu Shen, Xuguang Wang · Engineering Blasting · 2005
The vibration testing analysis of blasting Tai-Chang freeway(Taiyuan-Changzhi) shows that chamber deep-hole pre-splitting blasting can strikingly drop the seismic effect of chamber blasting,effectively solving some problems of slop stability,slop quality and safety of building structure that blasting vibration brings about.The improved technique of chamber blasting is beneficial to the extending of its scope of applications,and provided references for the similar engineering.
