| 摘 要： | 溪洛渡水电站导流洞围堰拆除是国内第1个关门冲碴爆破实例,且是在堰前高水头高水流流速条件下爆破,由于爆后不具备机械清碴条件,需要依靠水流冲碴,还要保证周围建筑物的安全。本工程通过水力学模型试验,确定了实现冲碴的爆破块度特征、爆堆形状和飞石范围,据此建立了爆破设计原则和方法,并应用精细爆破技术进行了个性化爆破设计,成功地解决了上述难题。

| Abstract: | The diversion tunnel cofferdams at Xiluodu hydropower station are the first blasting demolition case that closes gate and washes stone slag in domestic.There were as follows problems for their blasting demolition that their blasting demolition would be carried out under high water head and high water flow velocity,have not conditions of cleaning slag by machine and rely on water flow to wash stone slag after blasting,and ensure the safety of buildings around.Through hydraulic model test,blasting block chara... |
