摘　　要：白鹤滩拱坝溢流表孔共6孔,单孔净宽14 m,为白鹤滩拱坝重要泄洪建筑物。表孔结构复杂,坝址地震烈度高,采用三维有限元法针对不同工况下表孔进行静动力计算。根据应力计算结果,合理布置钢筋,使表孔结构满足承载力及正常使用要求,可为相似工程提供工程经验。Baihetan arch dam has 6 surface orifices and the net width of each is 14 m.They are the most important flood discharge structure of Baihetan arch dam,and the structure of surface orifice is very complex.3 D finite element method is used to analyze the static and dynamic characteristics of the surface orifices under different working conditions.According to the stress calculation results,the reinforcement is reasonably arranged to make the surface orifice structure meet the requirements of bearing capacity and normal operation,which provides engineering experience for similar projects.
