- 摘要:
- 为了保证新建隧道下穿既有G316道路施工中的安全性，采用现场监测的方法对隧道爆破掘进产生的振动进行实时监测，并根据采集的爆破数据回归分析，确定了修正的多孔爆破质点峰值振速计算公式中的相关参数k和α。研究结果表明：采用修正公式计算的质点峰值振速与现场监测结果最小误差为1.92%，最大误差为25.34%，平均相对误差为13.88%，说明修正的多孔爆破质点峰值振速计算公式是可行的。
- Abstract:
- In order to ensure the construction safety of the new tunnel downtraversing the existing 316 National Road, the field monitoring method was used to monitor the vibration caused by the blasting tunneling of the tunnel in real time. According to the regression analysis of the collected blasting data, the relevant parameters and in the modified calculation formula of the peak particle vibration velocity by the multihole blasting were determined. The results showed that the minimum error between the peak particle vibration velocity calculated by the modified formula and the field monitoring results was 1.92%, the maximum error was 25.34%, and the average relative error was 13.88%, which proved that the modified calculation formula of the peak particle vibration velocity by the multihole blasting was feasible.
