摘要
水下岩塞爆破是一种干扰较小、适用性强、比较经济的施工技术,在国内外已被广泛应用。本文以长甸水电站改建工程为依托,结合实际情况分析了施工的关键点、重点和难度,对岩塞爆破方式进行了比选,并阐述了岩塞爆破参数设计、装药结构设计、起爆网路设计等技术控制要点,可为类似工程提供借鉴。
Underwater rock plug blasting is a construction technology with less interference as well as strong applicability and economy,which has been widely used at home and abroad.The key points,emphasis and difficulty of construction are analyzed by combining with actual condition based on the reconstruction project of Changdian Hydropower Station in the paper.The rock plug blasting methods are compared and selected.The technical control keys of rock plug blasting parameter design,charging structure design,initiation network design,etc.are described,thereby providing reference for similar projects.
