| 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。

| Abstract: | 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 different 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 deformation of rockfill dam law and consistent with monitoring results. |
