摘要
介绍了特大体积闸墩爆破拆除时爆破参数的选取和实施方法。新老闸墩一端仅隔 4cm ,利用钻孔爆破法拆除老闸墩取得了快速、经济。
The selection of the blasting parameters and the implementation scheme in demolition of an out size pier close to a protected pier is introduced. Since the distance between the two piers is only 0.04 meters , the demolition by drilling blasting is very efficient because of its high speed, low cost and safety.
