Description

technical field [0001] Embodiments of the present invention relate to related technical fields such as hydropower engineering, parameterized design, and gravity dam optimization design, and in particular, to a method, device, and electronic equipment for optimizing a non-overflow section of a gravity dam. Background technique [0002] Although the design work of concrete gravity dams has relevant design standards as reference, the standards only stipulate the safest values ​​of some design parameters. In the actual design process, specific factors such as topography, geology and economy need to be considered in order to meet the design standards. The design parameters are further adjusted and optimized to meet the actual needs of the project. At present, for the design optimization of non-overflow dam sections of concrete gravity dams, most of them are converted into nonlinear programming problems under multiple constraints to solve. way to optimize the design parameters. ...
