摘要
爆破是一种巨大能量瞬态对介质的作用过程。爆破地震效应、爆破冲击波、爆破飞石被公认为是爆破破坏作用的"三大公害"。结合工程实际对不同类型爆破地震效应的测试,进而分析其质点振动速度在不同高程差对建筑物或构筑物的安全影响,并据此指导调整爆破孔网参数,确保在复杂地形环境条件下土石方开挖爆破的安全实施,取得了较好的经济效益和社会效益。
Blasting is a process of an instant impact of huge energy release on medium. The seismic effect, shock wave and flying rock induced by blasting are commonly recognized as ＂three great public hazards＂ due to the destruction function of blasting. In combination with a practical engineering, the seismic effect of various types of blasting was studied / and the effect of its different particle vibration velocities at various altitude differences on the safety of buildings or structures analyzed. Based on this, the blasthole pattern parameters were regulated so as to ensure the safe execution of the excavation blasting under complex topographical environment conditions, which has achieved good economic and social benefits.
