在最近几年中间,我们和一些兄弟单位协作,用空间等参数单元计算过几个拱坝,并计算过蜗壳、闸墩等水工结构。在计算过程中,出现过一些需要澄清或需要解决的问题。我们对其中的若干问题进行了分析,提出过一些意见和解决问题的办法,也计算过几个实例以资验证。现将所得成果作简单的介绍,请批评指正。为了便于查阅,在附录中列出了本文用到的公式,编号(101)至(107)。 In the middle of recent years, we have worked with some fraternal units to calculate several arch dams with spatial parameters and calculate hydraulic structures such as volutes and piers. During the calculation, there have been some issues that need clarification or need to be resolved. We analyzed some of these issues, put forward some opinions and solutions, and also calculated several examples to verify. Now we will briefly introduce the results obtained, please criticize and correct me. For ease of reference, the formulas used in this paper are listed in the appendix, numbers (101) to (107).
