洛惠渠拱坝结构三维有限元分析

3-D Finite Element Analysis of Luohuiqu Arch Dam

采用线弹性有限单元法,用有限元分析软件ANSYS对洛惠渠拱坝进行了多工况多方案分析研究。并对计算出的大坝应力和变形状态进行分析,计算结果表明,坝体应力分布合理,基础变形模量在一定范围内上下浮动对坝体应力影响不大,为大坝的加固改造提供依据。

Multiple loading cases and calculating schemes of Luohuiqu arch dam is analyzed by using ANSYS which is the software of the finite element method （FEM）, and the results of the stress and deformation of the dam are analyzed. The results show that the stress and deformation distribution is reasonable and the variation of deformation module of the foundation in a certain range produces little influence on the dam stress, so it could provide the basis for the strengthening and remodelling of a dam.
