| Abstract: | 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. |
