摘要
应用土与结构动力相互作用理论,基于ANSYS软件建立了围岩—水工地下隧洞结构非线性动力相互作用的有限元分析模型,采用整体有限元分析方法对隧洞衬砌结构进行了地震时程反应的数值分析。分析了衬砌弹模、围岩类别以及地震波频率对洞室位移和应力响应的影响。
By using ANSYS software and applying the theory of soil-structure dynamic interaction, the nonlinear dynamic wall rock-hydraulic underground tunnel interaction is modeled. Seismic time-history response of the tunnel is numerically analyzed by applying whole finite element approach. The paper mainly analysed the response of the stresses and displacements on the impact of wall rock types, elasticity modulus and seismic frequency.
