龙首水电站预裂爆破试验研究

预裂爆破的钻孔精度是预裂爆破的前提，它仍是工程上应严格要求和控制的重要因素。龙首水电站左右岸开挖爆破采用仪器监测，结合生产进行了一系列实验。主要介绍了现场预裂爆破试验的方法和措施，结合生产，研究分析了预裂爆破效果及影响，为爆破的设计和施工提供技术参数，可作为同类工程的参考。

Experimental Research of Pre-splitting Blasting at Longshou Hydropower Station

Drill precision is premise of the pre-splitting blasting, it is strict requirement and controlled key factor in the engineering. The Longshou hydropower station around land excavation adoption to instrument monitoring, and combined with production made a series of experiment. The simulative field pre-splitting blasting experiment, the pre-splitting blasting effect was studied, some parameters and bases are offered for design and construction of the pre-splitting blasting in this disquisition and the practice could be used for reference for similar project.
