狼猫山水库溢洪道改建工程爆破施工

Explosion Construction in Spillway Reconstruction of Langmaoshan Reservoir

在狼猫山水库溢洪道改建施工中，针对开挖、拆除爆破对周边建筑物安全的影响进行了分析．本工程对爆破的检测手段分宏观和微观两种；爆破施工分现场试验性爆破和施工爆破两个阶段，从爆破施工的检测资料分析得到了本工程爆破振动的衰减规律及坝体的振动响应．结果表明，狼猫山水库溢洪道改建施工，较好地处理了爆破施工对周边建筑物的影响，保证了大坝安全运行．

While reconstructing the spillway of Langmaoshan Reservoir, the explosive effect of excavation and removal construction to the safety of neighboring buildings was analyzed. The means of detection include macro-and-micro examinations. The explosion comprised of testing and practical explosion. The decrement laws of explosional vibration and vibrational reflection of this project were obtained by analyzing the detection data of the explosion. The reconstruction effectively diminished explosive effect on neighboring buildings and guaranteed dam safety.
