摘要
文章就混凝土拱坝考虑混凝土浇筑过程,分缝分块及封拱等程序引起的效应进行分析,并举出算例运用有限元计算软件Ansys对考虑施工过程以及不考虑施工过程的混凝土拱坝进行自重应力计算分析比较,得出有益结论。考虑施工过程的混凝土坝体更能体现实际工程的情况,为拱坝设计阶段提供可靠依据。并对拱坝结构计算研究具有一定的参考价值。
The text analyzes effects of concrete pouring, blocking and closure on the construction of an arch dam. Self-weight stress calculation through finite dement calculation software Ansys is made on concrete arch dams with and without consideration taken to construction process, and calculation results are compared. It concludes that concrete dam engineering considering construction process reflects practical situation of a project more comprehensively and provides reliable references to design and structural calculation of the arch dam.
