综合减震技术在紧邻运行核电爆破施工的应用

红沿河核电站二期GD廊道距商运的4#核电机组较近,爆破阈值较小,通过对爆破震动理论进行深入的研究,决定采用综合减震技术。经现场监测,在GD廊道爆破开挖过程中起到了很好的减震效果,为后期类似环境施工提供了有力的借鉴。

The GD corridor of Hongyanhe Nuclear Power Station Phase Ⅱ is close to the commercial 4 # nuclear power unit, with a small blasting threshold.The synthetic damping technique is adopted after the deep research of blasting vibration theory .After on-site monitoring, it has played a good effect of shock absorption in the process of GD corridor blasting excavation.
