摘要: |
以最大主拉应力最小作为目标函数,建立了拱坝体型优化设计的线性规划模型.以该模型计算某高拱坝的结果表明,以应力为目标的拱坝体型优化设计,可合理地调整坝体应力状态,从而获得更高的安全储备. |

Stress-oriented shape optimization of arch dams based on linear programming model |
JIN Hai1,LIN Gao1,YANG Ming-sheng2

Abstract: |
A linear programming model for the shape optimization of arch dams is established to minimize the maximal tensile stress of the arch dam. Calculation results of an arch dam show that the stress-oriented shape optimization design method can rationally adjust the stress state of the dam so as to reach a higher safety factor. |
