本文结合某供水工程隧洞布置实际情况,在动力计算理论基础上,运用有限元Midas/Gts动力分析模块对爆破冲击荷载作用下隧洞施工中既有隧洞的三维动力响应进行分析。为该隧洞的设计与施工提供一定价值的指导。
Based on the theory of dynamic calculation and the finite element Midas / Gts dynamic analysis module, this paper analyzes the three-dimensional dynamic response of the existing tunnel in tunnel construction under blasting impact load. Provide some guidance for the design and construction of the tunnel.
