【摘要】 作为一种大型挡水建筑物结构形式,拱坝(Arch dam)以其合理的力学结构和支撑体系所表现出的经济性和安全性成为当今大坝设计中的三大优选坝型之一;但是由于坝型曲线种类多、工程规模大、造价高、建造周期长,设计、计算、绘图、施工均很复杂。鉴于拱坝设计计算和施工技术的复杂性,计算机辅助设计在拱坝设计中的应用越来越广泛,要求也越来越高。具有友好的交互式用户界面、高效的数据管理能力、高度的软件集成是目前拱坝设计分析软件开发中的重要研究课题。本文基于可视化和参数化的思想,按照拱坝设计规范的要求,研究面向拱坝对象的编程技术、可视界面设计技术和图形处理技术,结合实际需要设计和开发了拱坝三维可视化设计与制图软件系统。该软件系统以Auto CAD Civil 3D为开发平台,充分运用VB.NET, VLisp,ObjectARX等开发语言,采用面向对象的编程技术以及ADO数据库开发技术,解决了不同软件之间的数据对接问题。该系统使用方便、界面友好、运行可靠,在设计生产中起到了重要的作用。更多还原

【Abstract】 As large-scaled hydro curved structures, double-curved arch dams maintain the characteristics of various dam curves, large scale, high cost and long construction cycle. Designing, calculating, drafting and constructing related to them are rather complicated. As a result, no one can construct such a structure successfully just through simple sample amplifying or designing and calculating. As one of the most important steps in designing and constructing an arch dam, arch dam construction layout and graphics processing are crucial to the project quality and construction process. Any mistake or error in any of the procedures will be likely to cause great loss. In light of the complexity of designing and constructing technology, computer-aided design is more and more widely used in designing arch dam, and the requirements are also improved constantly. So such software as those which have friendly interactive user interface, efficient data management and highly software integration are the most important research projects in current arch dam designing and analyzing software development.Based on the idea of visualization and parameterization, the requirements of arch dam design regulations and practical needs, the project aims to develop 3D visual arch dam designing and drawing software system through integrating Object-oriented Programming Techniques (OOPT), Visual Interface Design Techniques(VIDT) and Graphics Processing Techniques(GPT). Adopting VB.NET, the developing techniques and tools of Auto CAD, OOPT and DAO Database Developing Technique, we have developed the basic Auto CAD drawing modules. The designing and drawing platform of this software system is Auto CAD Civil 3D, and its development environment is Visua1 Studio.NET 2005 integrated with VBA. Its convenience, friendly interface and reliable operation have helped this software to play a key role in design and production更多还原
