摘　　要：龙江水电站枢纽工程大坝为椭圆混凝土双曲拱坝,坝基地质条件较复杂,坝址区地震基本烈度为Ⅷ度。设计进行了大量的分析、研究工作,通过拱坝体形优化、坝体应力分析、坝肩抗滑稳定分析,选用椭圆混凝土双曲拱坝,既保证了工程安全,又减少了大坝混凝土方量,节省了投资,为工程的开工建设奠定了基础。The dam of Longjiang hydropower station is concrete elliptic double-curvature arch dam.The geological condition of dam foundation is complex.Seismic basic intensity of dam-site is eight degree.Based on a lot of analysis and study work,the concrete elliptic double-curvature arch dam is selected by arch dam shape optimization,dam stress analysis and the stability analysis against sliding of dam abutment,which could ensure project safety,decrease volume of dam's concrete,save investment and lay foundation of project construction.
