摘要
提出了抛物线双曲拱坝有限元网格剖分的算法 ,即用密切圆包络切线法计算拱弧曲线、按径向扭缝或铅直面横缝计算竖直拱梁曲线的一套方法。
A complete set of algorithms to divide finite element network is presented for parabolic double curved arch dam The set involves in calculating arch arc curve by using “osculating circle envelope tangent method” and vertical arched beam curve by “radial contortion fissure” or “transverse joint of vertical plane” An applied software system CADCS for the dam is developed based on the algorithms stated The calculation and graphing of Laxiwa arch dam on Yellow River are completed by applying this software with very good results
