摘要
深孔预裂爆破技术已广泛用于水利水电工程建设石方明挖边坡开挖施工,主要在石方明挖预裂爆破技术的基础上研究和实践深孔预裂爆破技术在水利工程特大型断面导流洞中层开挖施工过程中的应用。结合东庄水利枢纽工程,通过合理选择爆破设计参数、施工工艺及施工方法,在安全、快速、保质、高效的情况下,实现经济效益最大化。
Deep hole presplitting blasting technology is widely used in slop construction of rock open excavation on water resources and hydraulic engineering.Combined with Dongzhuang water control project,this paper mainly studies and practices that this technology is applied in middle-layer excavation construction of super huge type cross section diversion tunnel on water conservancy works on the basis of rock open excavation,in order to realize economic efficiency maximization by reasonable blasting design parameters,construction technology and method statement under the condition of safety,high speed,high quality and high efficiency.
