摘要
三峡电源电站地下厂房岩锚梁开挖施工,采用双向光面控制爆破技术一次开挖成型,就该工程岩锚梁开挖时机选择、钻孔精度的控制、爆破设计方案等进行论述,检测结果表明,所采用的施工方案科学、有效,满足设计开挖要求.
A double-direction controlled formed and smooth blasting technology was used to excavate an anchored rock beam in the underground powerhouse at the Three Gorges Power Supply Plant. Some problems concerning the time choice, accuracy control and design solution for the blasting were discussed. The results of investigation have showed that the method developed is scientific and effective, enabling to satisfy the excavation requirements by designers.
