摘要
采用三维有限元方法,分析了双曲砌石拱坝在不同工况下的变形和应力变化规律,以了解坝体在设计条件下的工作性态和对坝体的抗震安全性能进行评估。结果表明,坝体的应力及变形基本满足承载要求,其结论和成果对于其他同类拱坝结构分析具有参考价值。
The laws of deformation and stress change a double-curvature stone masonry arch dam dam body under various working conditions are studied by the three-dimensional finite element method,so as to understand the working situation of the dam body under design conditions,and the seismic strength of the dam is evaluated.Calculated results show that the requirements for the dam′s stress and displacement can be met,the conclusion and achievements of the dam have important reference value for the similar projects.
