拱坝体形优化的有限元分析研究

摘要

The article takes the shape of logarithmic helix arch. The stress analysis and shape optimization are performed with the finite element analysis. It is based on the multi-arch beam method design and is taken for example in putting forward a solution to its shape optimization. The key problems in arch dam design is about the shape optimization,the research of which is essential to the design's security and to lowering the costs.%选择对数螺旋拱圈,以拱梁分载法为基础,采用有限元方法进行拱坝应力分析和体形优化,提出拱坝体形优化方案,对提高拱坝的安全度和降低造价、提高拱坝设计水平具有重要意义.
