| 摘 要： | 陆浑水库溢洪道泄洪闸墩基础0~1.0m以上需爆破拆除,距右墩21m处有一栋三层危房。在施工的过程中,采用了分层间隔装药结构和水平预裂爆破,通过现场试炮和震动效应观测,确定了爆破安全标准。根据试验结果对原来的爆破方案和爆破参数进行了优化,指导了施工,没有对危房造成进一步的危害。

| Abstract: | The foundation of the spillway pier of Luhun reservoir was projected to be demolished at its section of 0～1.0m above through controlled blasting.The problem was that there was a three-stories dilapidated building 21m far from the right pier.For this reason,the delaminated charging structure and the level presplitting blasting were adopted.Based on the results of site blasting experiment plus its vibration monitoring the designed blasting parameters and the blasting program were optimized,and the practical blasting was well instructed,leaving no further danger to the dilapidated building. |
