摘要
在岭澳核电站二期工程基础开挖现场爆破试验的基础上,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。并与一期工程得到的爆破震动衰减规律进行了比较,校核和优化了爆破震动参数,对后续爆破设计和施工具有指导意义。
On the basis of the groundwork digging and its blasting of the second-stage project in Lingao Nuclear Power Station and its field test, the measured vibration acceleration values and the measured vibration velocity values are regressed, 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 first-stage project in Lingao Nuclear Power Station. The blasting vibration attenuation law is helpful to design and excavation of future blasting.
