| 摘 要： | 基于三维有限元计算软件ANSYS对某一高145 m的混凝土双曲拱坝进行开设大表孔与不开设表孔方案的计算对比分析,通过分析得出,高拱坝坝顶开设表孔对坝体应力的影响是局部的,主要集中在孔口周边,而对坝体下部几乎没有影响。最后,总结规律,希望为拱坝结构设计及体形优化提供参考。

| Abstract: | Basing on 3D finite element software ANSYS,this article calculates a concrete hyperbolic arch dam whose height is 145 m,using opening large surface outlet plan and no large surface outlet plan to carry on contrastive analysis respectively,the following conclusions can be drawn through calculation and analysis: the surface outlet mainly influence the stress in the orifice vicinity,but have little contribution to lower part of dam body.Finally,the paper summarized the rule,hoping to provide reference for the ... |
