【Abstract】 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.更多还原
