深孔爆破震动对城市环境的危害及控制技术

Hazards of the City Environment on Deep - hole Blasting Vibration and its Control Technology

分析了爆破地震对周围环境引起的危害。通过爆破震动实时监测,用小波理论分析了深孔爆破震动特点。并对安全判据缺陷、实际应用中的考虑震动频率影响时安全判据选取原则及方法进行了探讨,提出了一套行之有效的爆破地震控制技术及参数设计方法,取得了很好的经济效益。

The blasting seismic wave propagating law, the control technique and the selection of security criterion attract close attentions. The blasting seismic hazards to the city environments are analysed in this article. Through monitoring blasting viberation in real time, the character of deep- hole blasting viberation is analysed according to the small - wave theory. The defects of safe criterion, the choosing rules and method of safe criteria considering the effect of viberation frequency are discussed at the ...
