1981年初我国水电科学技术赴美考察组了解到美国工程爆破的一些新动向,特简介于后。 (一)重视爆破振动影响控制,确保工程安全。美国垦务局设技和研究中心(U.S.Bureau of Reclamation of the Engineering and Research)于1980年制订出第一份水利工程爆破规程报告,供垦务局系统内部使用。报告中介绍了大坝在控制爆破影响方面的经验,讨 At the beginning of 1981, China’s hydropower science and technology mission to the United States learned some new trends in the engineering blast in the United States, especially after the brief. (A) attention to the impact of blasting vibration control, to ensure project safety. The U.S. Bureau of Reclamation of the Engineering and Research developed the first report on blasting procedures for hydraulic engineering in 1980 for use by the Bureau of Reclamation’s internal systems. The report describes the dam’s experience in controlling the impact of explosions
