摘　　要：对洞坪拱坝开孔前后的坝体结构应力变形状态作了三维弹塑性有限元仿真分析计算,并且进行了等效应力核算。计算结果表明,坝体应力变形满足安全要求。在整体大坝仿真的基础上,通过局部网格加密,重点对中孔部位的闸墩及弧形闸门深梁进行了有限元计算,为孔口处配筋提供了参考依据。Three-dimensional elastic-plastic FEM method is adopted to calculate dam stress and distortion of Dongping arc dam before and after perforate, and equivalent stress calculation is performed. The result shows, the stress and distortion satisfies safety requirement. And on the basis of the whole dam emulation analysis, through performed, which is the reference of reinforcing.
