摘要
基于三维有限元计算软件ANSYS对某混凝土双曲拱坝坝体应力分析,通过分析得出,拱坝最大位移发生在坝体表孔位置,但是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,并总结规律,为工程设计、施工和加固处理提供了重要科学依据。
This paper made stress analysis on a concrete hyperbolic arch dam based on three-dimensional finite element calculation software ANSYS, through the analysis gained, the largest displacement of arch dam occurred in the surface hole position of dam, but the influence of opening surface holes in darn head to dam stress were local, mainly concentrated in the outlets circum, had almost no effect to the dam. And summarized the laws, provided important scientifie basis to engineering design, construction and reinforcement treatment.
