摘要
通过对露天矿和井下矿的爆破振动的测试分析 ,提出了比较全面、科学的爆破振动安全判据建议标准。评价结构物爆破振动安全性时不能只考虑质点振动峰值 ,还应包括爆破振动频率 (结构固有频率和激励频率 )。爆破振动安全指标应包括位移。
Based on measurement and analysis of blasting vibration of surface mine and underground mine, all-round and scientific criteria of blasti ng safety are suggested. It is concluded that appraising the safety o f construction blasting vibration include not only peak value of mass point, but also frequency of blasting vibration(natural frequency and driving frequency of construction). The safety criteria of blasting vibrat ion consist of displacement, velocity and acceleration.
