摘　　要：基于大岗山拱坝地质条件复杂、地震烈度高,按照静载设计、动载复核的原则,对大岗山拱坝抗震设计开展了研究。通过计算分析和模型试验,采用布置梁向抗震钢筋、跨缝阻尼器、抗力锚索与坝基薄弱岩体灌浆等工程技术措施,提升了大岗山水电站超高拱坝的抗震稳定安全性。Dagangshan arch dam is of complex geological conditions and high seismic intensity.According to the principles of design with static loads and check with dynamic loads,the anti-seismic design of the dam is studied.Based on calculation analysis and model tests,engineering technical measures such as the arrangement of cantilever anti-seismic reinforcement,cross-joint dampers,resistance anchor cables,and grouting of weak rock masses in dam foundation are adopted to improve the seismic stability and safety of the dam.
