文献[1]曾经提出弹性厚壳曲面有限单元法的数学模型。这种方法从理论上看,要比试载法严密,从节省计算机存贮容量上看,要比三维有限单元法经济。由于拱坝中面是一个空间曲面,填写结点座标和上下游面座标差值时,手算工作量很大,严重影响这种分析方法的推广应用。本文的目的,在于对各种拱坝坝型,探讨一种自动生成几何参数的方法。计算时只要给出少量且容易提供的数据,就可通过程序自动生成所需要的几何参数。
Literature [1] proposed a mathematical model of finite element method for elastic thick shell and curved surface. In theory, this method is more rigorous than the loading method, which is more economical than the three-dimensional finite element method in terms of saving the computer storage capacity. Because the middle of the arch dam is a space surface, when calculating the difference between the coordinates of the nodes and the coordinates of the upstream and downstream surfaces, the workload of manual calculation is very large, which seriously affects the popularization and application of this analytical method. The purpose of this paper is to explore a method of automatically generating geometric parameters for various arch dam types. As long as the calculation given a small amount and easy to provide data, you can automatically generate the required geometry parameters.
