基于麻雀搜索算法的重力坝断面优化设计研究OA
Shape Optimization Design of Gravity Dams Based on Sparrow Search Algorithm
为了降低建造成本,在保证重力坝坝体稳定的前提下,对坝体断面进行优化设计.首先,以坝体断面面积为目标函数,以坝体抗滑稳定、坝踵与坝趾处应力为约束条件,建立重力坝断面优化的数学模型;然后,采用麻雀搜索算法对其进行优化求解;最后,以费县崔家沟水库重力坝为研究对象,将麻雀搜索算法所得到的优化结果与用差分进化算法所得到的优化结果进行分析比较,结果表明:麻雀搜索算法寻优能力更强,对重力坝断面优化的效果更好.
On the premise of ensuring the safety of the gravity dam body,to minimize construction costs as much as possible,the section of the dam body is optimized and designed.First,a mathematical model for optimizing the shape of a gravity dam is established,with the shape area of the dam body as the objective function and the anti-sliding stability of the dam body,as well as the stress at the dam heel and toe as constraints.Then,the sparrow search algorithm is used…查看全部>>
