| 摘 要： | 汶川地震的经验表明,高拱坝可能遭受远超其设计烈度的强地震作用.研究拱坝的地震损伤破坏情况,探究其地震超载潜力,对于防止发生严重的地震灾变具有重要意义.在拱坝的动力分析中,采用宏观均质假定基础上考虑混凝土细观非均匀性影响的地震损伤破坏模型,以及基于阻尼溶剂抽取法的拱坝-地基动力相互作用模型以考虑无限地基辐射阻尼的影响,研...

| Abstract: | As shown by the experience obtained from Wenchuan Earthquake,high arch dams are likely to experience ground motion much stronger than their design value.So it becomes extremely important for avoiding serious earthquake disasters to investigate the damage of arch dams subjected to earthquakes and examine their seismic overloading capacity.The damage of an arch dam subjected to earthquakes of different intensities is studied.The damage model for dynamic analysis of arch dams which incorporates the heterogenei... |
