摘要
本文对双溪口面板堆石坝在蓄水期采用三维非线性弹性有限元法进行了应力变形计算。观察坝体、面板的应力和变形情况,并就堆石流变对坝体、面板应力和变形的影响进行了分析研究。结果表明:考虑堆石的流变效应后,坝体变形有所增加,特别是对面板的应力变形状态影响很大。可见蓄水后的堆石料流变对面板堆石坝的安全影响重大。
3D nonlinear elastic finite element method is adopted in Shuangxikou face rockfill dam during impoundment period for stress deformation calculation. Stress and deformation of dam body and panel are observed. Influence of rockfill rheology on dam and panel stress and deformation is analyzed and studied. Results show that after considering the rheology effect of rockfill, dam deformation is slightly increased, and the influence on panel stress deformation state is great. It is obvious that the rockfill rheology has significant influence on safety of face reck：fiU dam after impounding.
