| 摘要: |
| 将结构的形式视为可变控制量，考虑结构的整体稳定生，安全性和经济性的要求，建立了弹性静结构的形式自控制模型，并采用离散一体化方法进行数值求解，以拱坝体型的静力自控制问题为例，对拱坝6种体型优化分析表明，当拱坝体型为一般二次曲线时，得到的自控制体型为最优。 |

| Abstract: |
| Taking the structure's type as a controlled variation, and considering demands of stability, safety and economy, a self-controlled model of an elastic static structure was established, and a numerical solution was obtained by optimization and discreteness. The shape design of an arch dam was taken as an example. Analytical results of optimized six types of dam shapes show that the self controlled shape is the most optimistic when a dam's shape is a general double curve. |
