摘要
在拱坝横缝中,设置跨横缝钢筋和阻尼器,可以在一定程度上控制高拱坝在强震作用下的横缝开度,增强拱坝整体性。以国内某高拱坝为例,基于在大型商业有限元分析软件ABAQUS平台上二次开发的拱坝有限元模型,结合已有的计算成果,系统比较了设置跨横缝钢筋和阻尼器的抗震效果,提出了两种措施组合的方案,可供工程应用参考。
Laying out joint-crossing reinforced bars and dampers in transverse joints can effectively control the openings of the transverse joints under strong earthquakes and intensify the integrity of arch dams. With a high arch dam in China taken as an example, a comparative analysis was performed of the aseismic effect of joint-crossing reinforced bars and dampers by use of the finite element model for arch dams further developed based on large commercial software ABAQUS and the obtained result from calculation. Finally, a scheme combining the two measures was proposed, providing some references for practical projects.
