【摘要】 以岭澳核电站采石爆破为背景,分析了采石场爆破对核电站、水库的振动效应及安全影响,并确定了核电站、水库的爆破振动安全阈值.在现场试验的基础上,对测得的振动加速度、速度数据进行了回归分析,得到了场地爆破震动衰减规律,并与核电站二期工程基础负挖爆破得到衰减规律进行了比较,校核和优化了爆破震动参数,对保证核电站、水库的安全以及后续采石场爆破设计和施工具有指导意义.更多还原

【Abstract】 On the basis of exploiting stone by blasting at quarry in Ling’ao Nuclear Power Station, blast in exploiting stone at quarry for vibration effect and safety effect of Nuclear Power Station and reservoir is analyzed. The safety threshold of blasting vibration on Nuclear Power Station and reservoir is ensured. On the basis of the field test, the measured vibration acceleration values and the measured vibration velocity values are regressed, and the blasting vibration attenuation law in this region is obtained. The parameters of blasting vibration are checked and optimized, compared with the blasting vibration attenuation law obtained in the second- stage project in Ling’ao Nuclear Power Station. The blasting vibration attenuation lawis helpful to ensure safety of Nuclear Power Station and reservoir, design and excavation of future blasting.更多还原
