文章作者采用三维有限元方法,对九井岗电站拱坝进行了整体空间应力应变分析,包括:建立拱坝三维静力分析模型,得到了其典型工况下的整体应力应变分布规律;根据计算结果,评价了拱坝结构的整体静力特性。本有限元计算结果为坝体体型设计与优化提供了依据,为大坝安全运行提供了保障。本文对拱坝体型参数、空间线弹性有限元计算成果作了简要介绍。
The author uses the three-dimensional finite element method to analyze the overall space stress and strain of the arch dam of the Jiujinggang Power Station, including: establishing a three-dimensional static analysis model of an arch dam, and obtaining the overall stress-strain distribution under typical conditions; As a result, the overall static characteristics of the arch dam structure are evaluated. The results of the finite element analysis provide the basis for the design and optimization of the dam body shape, and provide a guarantee for the safe operation of the dam. In this paper, the finite element calculation results of arch dam body shape parameters and space line are briefly introduced.
