| 摘 要： | 通过引进拱坝三次样条曲线拱圈线型,建立了其计算模型和优化模型,并根据非线性规划可行域与最优解的理论,证明了各种线型拱圈的优劣。在此基础上,采用复合形法,分别对抛物线、椭圆、双曲线和三次样条曲线拱圈进行了优化。计算结果表明,所建模型合理可行,三次样条曲线拱圈具有明显的优势。

| Abstract: | Through the application of the type of cubic spline arch ring to arch dam, the computational model and the corresponding optimization model are established.Based on the theory of the doable region and the perfect resolution of non-linear programming,the parabola,ellipse,hyperbola and the cubic spline arch ring are respectively optimized according to Complex Method.The results show that the model is reasonable and reliable,and the cubic spline arch ring has obvious ascendent. |
