高拱坝新型合理体形的研究和应用

对动力优化,多目标优化,新体形及周边缝等的攻关研究,在已有的拱坝优化的基础上,从多拱梁优化发展到有限元优化,从静力优化发展到考虑地震荷载的动力优化,从单目标优化发展到双目标优化和多目标优化,发展和完善了我国提出的建立在拱坝优化的基础上的二次曲线及混合曲线拱坝新体形;使拱坝优化技术能适应高拱坝的体形设计,为小湾,溪洛渡等水电站的设计提供了参考,保持并扩大了我国在国际上拱坝体形设计领域的领先优势。

Study on and application of new rational dam-body shape of high arch dam

The study on the dynamic optimization, multi objective optimization, new dam body shape and peripheral joint have been developed, on the basis of existing arch dam optimization, from multi arch beam to finite element optimization, from static optimization to dynamic optimization taking earthquake load into account, from single objective to double and multi objective optimization. This study develops and perfects, on the basis of arch dam optimization, the conic and mix curvature new shapes of arch dam body that were put forward by Chinese technicians. It enables the arch dam optimization technology to adapt to the shape design of high arch dam, provides the reference for the design of Xiaowan and Xiluodu hydropower stations, and keeps and enlarges the our leading position in the design of arch dam shape in the world.
