| 摘 要： | 本文提出了抛物线双曲拱坝中轴线的几何定义及其计算方法，并对由此而引起的横缝设计作了说明。解决了工程设计中对抛物线拱坝中轴线用近似曲线代替所造成的理论缺陷和引起的计算误差。本算法对于拱坝横缝设计、应力计算、施工放样和计算机图形处理均有实用意义。

| Abstract: | Paper presents an integrated exposition for definition and algorithm of centeraxis in the domed parabolic arch dam. It eliminates the calculatede error and theorotic defectwhich are caused hy center axis of the arch dam being replaeed by approximate curve in the engineering design . The algorithm has practical significance in the design of transversejoints ,stresses calculation ,construction lofting and computer graphics of the parabolic archdam . |
