摘　　要：采用有限元分析方法,分析计算了地震波作用下瀑布沟电站泄洪洞出口段2-2剖面岩体与衬砌结构的变形、应力及加速度特性。计算表明,地震作用下动破坏区及衬砌内偏压现象均有显著增加。依据其动力破坏区发展深度,提出了抗震加固处理措施。Finite element method is used to analyze and calculate deformation, stresses and acceleration of rock mass and lining structure in cross section 2-2 at outlet of spillway tunnel under seismic wave action in Pubugou project. The calculation results indicate that bias pressure increases remarkably in dynamic failure zone and the lining under seismic action . Anti-seismic stabilization measures are proposed according to depth of the dynamic failure zone .
