摘　　要：爆破振动为爆破公害之首,工程上需要对其进行控制.基于爆破振动全历程预测的爆破振动控制方法是一种主动的控制方法,且具有良好的应用前景,本文阐述了爆破振动全历程预测的研究进展与应用,并对各种预测模型的优缺点进行了比较.介绍了两种典型的爆破振动主动控制方法——干扰降振法和频谱控制法的理论试验研究及其在工程中的应用,并重点分析了爆破振动控制在电子起爆条件下的优势及一些应用实例.最后指出了今后需要进一步研究的问题.Blasting vibration is major evil effect of blast pollution and should be controlled in engineering applications. Blasting vibration control technique based on full time-history prediction of blasting vibration is an active way to control the vibration and has a good prospect in application. In this paper the development and application of the blasting vibration full time-history prediction are discussed, and advantages and disadvantages of different prediction models are compared. The theoretical study, experimental research and engineering application of two typical active control techniques, i.e. vibration reduction method via waveform interference and spectral control method, are presented. And the advantages and some application examples of blasting vibration control under electronic trigging condition are described in detail. The problems in need of further studies are pointed out at the end of paper.
