核电站扩建工程基坑开挖爆破振动安全控制

Safety Control on Blasting Vibration in Foundation Pit Excavation of Nuclear Power Plant Extension Project

结合秦山核电二期扩建工程,在已运行核电站附近新扩建核电站的大型基坑开挖过程中进行爆破振动的监测与爆破振动的控制。通过理论分析与监测等多种手段对爆破振动进行有效的控制,确保了正在运行核电站的安全。所总结的减震措施经验对其他核电站的爆破振动控制具有借鉴作用。

According to the Qinshan nuclear power plant 2nd phase extension engineering,the monitoring and control on blasting vibration were made in the large foundation pit excavation of new expansion nuclear power plant near the operated one.The effective control on blasting vibration was realized by theoretical analysis and monitoring,and the security of the operating nuclear power plant was ensured.The vibration absorption measures summarized in this paper could be reference to blasting vibration control of other nuclear power plant.
