爆破振动效应不仅与爆破本身相关,而且还与爆破区域的地质条件密切相关,尤其是爆破近区.结合溪洛渡水电站坝基开挖爆破,分析了爆破近区裂隙结构面对爆破振动速度传播的影响,提出了考虑裂隙结构发育的质点振动速度传播规律的修正经验公式.溪洛渡工程的实践表明,修正的经验公式计算值更接近实测值.

The effect of blasting vibration is not only related to blasting itself,but also to the geological conditions of the blasting region,especially near the blasting region.This paper analyzed the influence of the dissemination of blasting vibration velocity by fracture and structural plane near the blasting region with the combination of blasting excavation of Xiluodu Hydroeleetrie Power Station dam foundation,proposed the correction regression formula considering the fracture and stmctural plane.Practice of Xiluodu Hydroelectric Power Station has proved that the calculated value of conrrection empifical formula is closer to measured values than empirical formula.
