摘要

在拱坝体型的优化设计中 ,传统的以经济指标为目标函数的数学模型 ,有一定的局限性。本文综合考虑拱坝的安全性与经济性 ,建立了多目标优化设计的数学模型。模型解决了多目标函数及拉应力控制标准的模糊性。小湾拱坝的优化计算结果表明了模型的合理性与可行性
In the arc dams optimization, the used mathematical models with the economic norms as their objective function have some extents of limitations. For the sake of comprehensive, safety and economy, a new multi\|objective optimization model is established. In this model, the fuzziness of multi\|objective function and the tension stress control criterion are all solved. The computation results for Xiao wanae dam demonstrate the model to be reasonable and feasible.
