摘　　要：爆破施工在工程建设中应用广泛,但爆破施工产生的震动也会对施工场地周边建筑物的安全和稳定造成不利影响。本文通过对碾盘山水利水电枢纽工程右岸船闸预开挖石方爆破震动监测及振动影响安全验算,界定了爆破作业对周边建筑物的影响范围,并简要分析了石方爆破震动对右岸高压电塔及附近村居民房的影响。根据震动监测及安全验算,本工程的爆破不会直接导致电塔破坏及周围民房结构性损坏。Blasting construction is widely used in engineering construction,but the vibration produced by blasting construction has a negative impact on the safety and stability of the buildings around the construction site.The impact scope of blasting operation on the surrounding buildings is defined through the vibration monitoring and vibration impact safety checking calculation of the pre-excavation of the shiplock on the right bank of Nianpanshan water conservancy and hydropower project in the paper,and brief analysis is made on the influence of rock blasting vibration on the right bank high voltage tower and nearby village houses.The blasting of the project will not directly cause damage to the high-voltage tower and structural damage to the surrounding village houses according to the vibration monitoring and safety checking calculation.
