| 摘 要： | 拱坝水平拱圈型式从早期的圆形逐步发展到变曲率的二次曲线,二次曲线中的椭圆拱坝具有适应性强、坝体体积小等优点,但受某些条件的影响,椭圆拱坝在我国才刚刚兴起。通过分析我国椭圆拱坝的发展过程,积极倡导选用椭圆拱坝,以推动拱坝线形发展、节省投资。

| Abstract: | The form of arch bam horizontal arch ring developed from the early round to the conic of variable curvature,the variable curvature arch bam has the advantages of strong adaptability and small volume.Due to the effect of some factors,the elliptic arch dam just started in China.Through analyzing the development of elliptic arch dam in China,promoting the linear evolution of arch dam and saving the investment. |
