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。
An algorithm for mesh generation of parabolic double-curvature arch dam based on finite element method is presented. One is the method of calculating arch curves by using tangent circle envelope method and the calculation of vertical arch curves by radial or transverse facets.
