本文总结了作者把拱坝优化这一新技术成功地应用于实际工程的经验。以前,拱坝优化的研究工作虽较活跃,但一直未能应用于实际工程,其原因主要是由于数学模型未能实用化。作者建立了拱坝优化的合理而实用的数学模型,包括6种实用的几何模型以及与拱坝设计规范完全协调的约束函数,并大力在水利水电系统中推广。使拱坝优化成功地应用于近30个实际工程,其中包括高度超过250m的2个设计中的最高拱坝,取得了巨大的经济效益和社会效益。完全用优化方法设计的瑞洋拱坝已竣工蓄水3年多,运行正常。
This paper summarizes the author’s experience in successfully applying the new technique of arch dam optimization to practical engineering. In the past, the research work on arch dam optimization has been more active, but it has not been applied to practical engineering. The main reason is that the mathematical model has not been put into practical use. The author has established a reasonable and practical mathematical model of arch dam optimization, including six kinds of practical geometric models and constraint functions fully coordinated with arch dam design codes, and popularized it in water conservancy and hydropower systems. The arch dam optimization has been successfully applied to nearly 30 practical projects, including the highest arch dam in the two designs with a height of more than 250m, which has achieved tremendous economic and social benefits. The Ruiyang Arch Dam, which is completely designed with optimized methods, has completed more than 3 years of storage and is operating normally.
