摘要
马鞍山长江公路大桥接线路基工程K27+000~K27+195段施工,主要困难为如何减小爆破振动对尾矿库的影响。此段石方开挖采用"毫秒微差定向预裂爆破方法"进行爆破施工,通过合理的爆破设计及施工技术措施,监测爆破效果并优化相关参数,有效控制了爆破振动对凹山尾矿库的影响,确保了坝体的安全。
Based on the construction of Ma’anshan Yangtze River Highway Bridge connection subgrade K27 +000 ~K27+195,the main difficulty is how to reduce blasting vibrations of the tailings library.The rock excavation method of used the millisecond directional blasting and pre-spliting blasting.By way of reasonable blasting design and construction meas-ures,monitored the effects of the bursting and optimizing parameters,effectively controlled the blasting vibrations of Aos-han-Tailings Library,and ensured the dam safe.
