摘要
采用三维线弹性有限单元法对白鹤滩拱坝进行了多工况多方案分析研究。计算结果表明,坝体应力分布合理,应力水平与同类拱坝相当,基础变形模量在一定范围内上下浮动对坝体应力影响不大。
Multiple load cases and calculating schemes of Baihetan arch dam is analyzed by use of 3-dimentional finite element method(FEM).Calculation results show that stress distribution on in dam is reasonable,stress level is comparable with alike arch dams,the variation of deformation module of foundation in certain range produces little influence on dam stress.
