摘要
在研究逆问题优化解的基础上,将信息化反演理论引入到隧道爆破开挖的控制参数反演问题中,建立隧道围岩控制爆破参数的反演模型。运用该模型对朝东岩隧道施工过程中的爆破控制参数进行了反演,获得了最大振速反演公式,计算结果与实测结果基本一致。
Based on the optimized solution of inversion problem, the information inversion theory was taken for inversing the blasting parameters of highway tunneling. An inversion model of tunnel surrounding rock blasting parameters was proposed. This model was applied in Chaodongyan tunnel project and the surrounding rock blasting parameters were inversed during tunnel blasting excavation. The calculation formula of the maximum vibration velocity was proposed and the theoretical calculating results are consistent with the field monitoring results.
