摘要
介绍了介休石虹大桥控制爆破的方案选择和参数确定。通过对该桥稳定性的分析,只在桥梁的重要承重部位布置炮孔,充分利用桥梁失稳后自重作用下的解体破碎效应,不仅减少钻孔数量,而且减少炸药单耗,取得良好的爆破效果和经济效益。
The blasting plan and blasting parameters of the demolition of Jiexiu Shihong bridge were introduced. On the basis of analyzing the bridge＇s stability,the boreholes were only arranged in the main load-bearing parts of bridge, and the disintegrated and smashed effects which were caused by the falling of the bridge due to losing its stability were fully utilized. As a result the number of the borehole and the amount of explosives had been reduced ,while good results of blasting and economics had been achieved.
