摘　　要：为了分析某水电站洞室爆破振动衰减规律及其对周围边坡稳定性的影响,对3个位置点进行振动测试,并对实测数据进行回归分析,分别得出3个位置点爆破地震波的衰减经验方程。利用这些方程可以有效地预测、评价爆破振动对边坡的危害,为爆破地震强度的预测和降震减震措施的采用提供了理论依据。In order to analyze cavern blasting vibration attenuation law in a hydropower station and its influence on the stability of surrounding slopes, the vibration tests on three locations are conducted. The seismic wave attenuation empirical equations of three vibration test locations are obtained by the regression analysis of measured data. These equations can be used to effectively forecast and evaluate the hazards of blasting vibration on slope and provide a theoretical basis to forecast blasting seismic intensity and implement shock damping measures.
