摘要
三峡电源电站工程施工中,对距三峡大坝仅11.9m的门机钢筋混凝土轨道地梁,采用了光面控制爆破进行拆除。本文就复杂环境下的拆爆设计思路、爆破参数选择等问题进行了论述。爆破效果表明,所采用的拆除施工方案科学、有效,满足了设计开挖要求。
In the excavation construction of power supply electricity station of Three Gorges, smooth controlled blasting was employed in demolition track ground beam of reinforced concrete only 11.9m away from the Three Gorges dam. In this paper, the design ideas of demolition of this beam through blasting together with the selection of blasting parameters were discussed. The blasting result showed that the employed design was scientific, effective, and met the requirements of excavation.
