抛物线双曲拱坝计算

An Algorithm for Arch Dams of Parabola Double Curvature

拱坝是一种经济、优越的坝型,在我国水电工程建筑中被广泛采用。抛物线双曲拱坝是其中的一种。利用计算机辅助设计方法,针对抛物线双曲拱坝分层分块计算提出了一种新算法——密切圆包络曲线法。以基本体型参数为初始条件,进行了水平拱弧曲线计算及拱坝分缝计算。此法概念明确,计算简便而精确,为拱坝工程设计、施工、计算机图形处理所实用。

Arch dams are economy and superiority dams. They are widely used in hydraulic and electrical engineering buildings. Arc dam of parabola double curvature belongs to them. With the aid of computer, an algorithm is presented in the article , for the laminate and parting calculation of arch dams parabola double curvature ——The method of the envelope of the family of osculation circles. Based on the original form and structure parameters, an algorithm of horizontal arch curve and parting of arch dams have been made. This method with clear concept is convenient and accurate in calculation. It could be used for the engineering design, construction and computer graphics processing of arch dams.
