摘　　要：基于《城市区域环境振动标准》(GB 10070—88)和《城市区域环境振动测量方法》(GB 10071—88),进行了露天深孔爆破工程振动测试。通过对测试数据的处理与分析,计算了振动加速度振级,探讨了露天深孔台阶爆破引起的环境振动特性及传播规律。结果表明:在段药量相同时,随着测点与爆心距离的增加,加速度振级将逐渐降低;对于同一测点,随着段药量的增加,加速度振级将逐渐增大;高频振动分量的振级衰减较快,低频振动分量的振级衰减较慢。Based on the Standard of Environmental Vibration in Urban Areas （GB 10070--88） and Measurement of Environmental Vibration of Urban Area （GB 10071--88）, the vibration tests in the openpit deep-hole bench blasting projects were carried out. The performance and the propagation law of vibration caused by deep-hole bench blasting in open pit were investigated through the processing and analysis of data measured and the calculation of vibration level of vibration acceleration. The results showed that： in the same dosage, the vibration level of acceleration would reduce gradually as the distance from the monitoring points to the explosion center increased; for the same monitoring point, the vibration level would increase gradually with the increase of dosage; and the vibration level of high frequency vibration attenuated faster than the vibration level of low frequency vibration.
