由于拱坝设计准则的逐步完善,拱坝设计方法、计算分析理论、手段的改进和计算机应用的普及,使设计者可从繁重的数值计算和绘图工作中解脱出来,用更多的时间去进行方案比较和论证。然而对于先进的分析方法,如果没有准确的数据输入,就可能得不到有用的结果,因此,要求设计者有丰富的拱坝建设知识,了解拱坝的发展历史,根据试验、原型观测以及工程类比得到切合实际的初始数据,这样才能作出符合实际的设计方案。所以在拱坝计算机辅助设计系统中,参考资料信息库是一个重要的组成部分。 Due to the gradual improvement of arch dam design guidelines, arch dam design methods, computational analysis theory, the improvement of means and the popularity of computer applications, designers can freed themselves from the heavy numerical calculation and drawing work and spent more time Program comparison and demonstration. However, advanced analysis methods may not yield useful results without accurate data entry. Therefore, designers are required to have rich knowledge on arch dam construction and to understand the history of arch dams. Based on experiments, prototype observation and engineering Analogy get realistic initial data, so as to make realistic design. Therefore, in the arch dam computer-aided design system, reference information database is an important part.
