摘　　要：为了探究水下爆破对陡坡水库岩质边坡振动影响,依托湖南炉慈高速皂市水库3#特大桥建设工程,开展岩石动力和水下爆破振动试验,利用数值模拟开展岩质边坡稳定性分析,研究工况下所产生的振动波速峰值均低于3.5 cm/s,证明在研究工况下水下爆破对边坡稳定性的振动影响较小,水下爆破既增强了对岩体的破坏效应,也减少了对边坡的扰动影响。The effects of underwater blasting vibrations on rock slopes in steep reservoirs are examined,with the study based on the construction of No.3 Extra-Large Bridge at Zaoshi Reservoir on the Hunan Luchi Expressway.Rock dynamics and underwater blasting vibration experiments are conducted,and numerical simulations are used to analyze rock slope stability.Results show that the peak vibration velocity under the studied conditions is below 3.5 cm/s,indicating minimal impacts of underwater blasting on slope stability.Underwater blasting enhances rock mass fragmentation efficiency while reducing disturbances to the slope.
