| 摘 要： | 以某已建工程为例,基于非线性邓肯E-B本构模型,建立了施工期坝面过水面板堆石坝的有限元模型,探讨了施工期坝面过水面板堆石坝的应力变形的分布与变化规律。计算结果表明：坝体应力变形主要是由自重引起的,汛期坝面过水引起的坝体附加应力变形较小,其结果都在合理的范围之内,面板堆石坝汛期采用坝面过水度汛是安全可靠的。

| Abstract: | Taking one built project for example, the article established a finite element model for overflow rockfill dam in construction period based on the nonlinear Dengken E-B constitutive model and discussed the distribution of stress-deformation and charge regularities of the overflow rockfill dam. The result indicated that the stress deformation of dam mostly was caused by deadweight, annex stress and strain of dam caused by the water upon CFRD was less in flood season, the result was reasonable, it was safe and reliable that flowing water through dam surface of CFRD in the flood season. |
