摘要
对高精度电子雷管减震的主要原理及效果进行研究。首先,利用波动理论分析了波形叠加达到干扰降振的条件。其次,从爆破地震波之间相互叠加干扰降振的原理出发,研究了毫秒延时爆破波形叠加干扰降振时延时间隔时差的计算方法。最后,将错相减震爆破设计应用到深圳地铁11号线基坑和隧道爆破工程中,取得了理想的减震效果。
This paper studied the main principles and effects of vibration-reducing with high-precision electronic detonator.The condition of achieving interference vibration-reducing by wave superposition was analyzed according to the wave theory,the calculation method of time delay interval for interference vibration-reducing by millisecond delay blasting wave superposition was studied based on interference vibration-reducing principle by blasting seismic wave superposition,and phase stagger vibration-reducing blasting design was applied to the foundation pit and tunnel blasting project in Shenzhen metro Line 11,which obtains the ideal damping effect.
