建立了拱坝体形优化的合理而实用的数学模型,提出了有效的求解方法,特别重视工程应用,目前已应用于近三十个实际工程,取得了巨大经济效益,并已应用于250米特高拱坝的设计。作者提出了一系列有效的求解方法,如内力展开法,设计变量指数变换法等等,并首次实现了地震荷载作用下拱坝的体形优化。
A reasonable and practical mathematical model for arch dam body shape optimization has been established, and an effective solution method has been proposed. Special attention has been given to engineering applications. It has been applied to nearly 30 actual projects and has achieved huge economic benefits, and has been applied to 250 meters. High arch dam design. The authors proposed a series of effective solution methods, such as the internal force expansion method, the design variable index transformation method, and so on, and for the first time realized the shape optimization of arch dams under the action of earthquake loads.
