Abstract

Large dams are a part of the infrastructure of any society, and a huge amount of resources are consumed to build them. Among the various types of dams, the optimum design of concrete gravity dams requires special attention because these types of dams require a huge amount of concrete for their construction. On the other hand, concrete gravity dams are among the structures whose design, regarding the acting forces, geometric parameters, and resistance and stability criteria, has some complexities. In the present study, an optimization methodology is proposed based on Sequential Quadratic Programming (SQP), and a computer program is developed to perform optimization of concrete gravity dams. The optimum results for 45 concrete gravity dams are studied and regression analyses are performed to obtain some explicit formulas for optimization of the gravity dams. The optimization of concrete gravity dams can be provided easily using the developed formulas, without the need to perform any more optimization process.

混凝土重力坝优化设计的新显式公式
大型水坝是任何社会基础设施的一部分,建造水坝需要消耗大量资源。在各种类型的水坝中,混凝土重力坝的优化设计需要特别注意,因为这类水坝需要大量的混凝土来建造。另一方面,混凝土重力坝是其设计在作用力、几何参数、阻力和稳定性准则方面具有一定复杂性的结构之一。本文提出了一种基于顺序二次规划(SQP)的优化方法,并开发了混凝土重力坝优化的计算机程序。对45座混凝土重力坝的优化结果进行了研究,并进行了回归分析,得到了一些明确的重力坝优化计算公式。利用所建立的公式,可以方便地对混凝土重力坝进行优化,而无需再进行任何优化过程。
