摘要
构造一对称拱坝作为对比拱坝,以白鹤滩拱坝为例,采用有限单元法对拱坝的地形不对称因素进行分析.结果表明,在地形不对称的影响下,随超载系数的增加,坝体有绕右坝肩作相对转动的趋势.与所拟的对称河谷对比体型相比,白鹤滩拱坝的超载能力有所降低.
The factors of topography asymmetry upon the arch dam are analyzed in the essay by finite element based on Baihetan Symmetric Arch Dam. Compared with simulated symmetry valley, the overload capacity of Baihetan Arch Dam is proved to be reducing with the increasing load, by rotating relatively around the right abutment under topography asymmetry.
