摘要
运用大型有限元商业软件ABAQUS分析白眉水库面板堆石坝有限元应力变形特性。坝体、坝基岩体分别邓肯E-B本构模型和线弹性模型,分别针对考虑基础变形和不考虑基础变形两种情况进行分析。计算结果表明坝体自身变形较小,而由砂卵石覆盖层引起的沉降所占比重较大,坝体的应力大小与堆石体自重应力较接近,计算成果符合堆石坝的一般应力变形规律,并且和监测成果吻合。
The finite element stress and deformation characteristics of Baimei rockfill dam with concrete panel was analyzed with large-scale finite element commercial software ABAQUS. The dam body and its foundation were analyzed with Duncan E-B constitutive model and the linear elastic mode respectively under two differ- ent situation of considering deformation and not considering. The calculation results show that dam itself has little distortion and the settlement caused by sand and gravel layer has a larger proportion, the stress of the dam is closer to rockfill gravity stress. The calculation results are consistent with the general stress and defor- mation of rockfill dam law and consistent with monitoring results.
