【摘要】 计算机辅助设计(CAD)技术以其设计工期短、设计质量高、设计成本低等优点已经广泛应用于各行各业中，但由于水利水电建筑物结构复杂多变的特点，水工结构CAD技术未能得到应有的发展。施工导流设计作为施工组织设计的核心，是确定施工进度计划及总体施工方案的基础，用CAD替代复杂的人工设计势在必行。 本文主要按照系统理论分析了明渠导流的特点和设计过程，按照程序设计结构化理论研究了用计算机辅助设计水工建筑物的一般思想，遵循以整体设计为主、局部详细设计的总体设计与局部设计相结合的原理，结合工程数据库技术和面向对象设计思想，以AutoCAD2000内嵌的VBA为开发工具，开发出了一套包括设计、计算、绘图、分析为一体的专业设计软件。本文借助机械装配的思想，提出了准装配式的设计模式。 本系统充分考虑软件设计可视化的要求，将各种命令和数据库操作进行了良好的包装，并采用了下拉式菜单结构来与用户接口，大大方便了用户的操作。经过上机试运行，结果表明该软件具有快速、准确、方便、实用等特点，具有一定的推广和实用价值。更多还原

【Abstract】 Although now the Computer Aided Design (CAD) has been broadly used in many projects because of its advantages such as shorter time, higher quality and lower cost of the designs, it has still not satisfied the users in hydroelectric engineering due to the complexity and variability of hydroaulic structure and construction. Construction diversion design, as a core of the hydroaulic construction organized design, is a basis of conforming construction schedule and whole scheme, it is imperative that the complicated manual design would be replaced with CAD technique.Following the system theory, this paper studied the design process of the channel diversion, analyzed the method of CAD to design the hydraulic engineering construction, and developed a software for the detailed design. And in virtue of the thoughts of mechanical assembly, a model of imitating assembly is presented.Based on the theory of structured program design, combined the database technique and the object-oriented program design idea, depended on the channel central line, the paper presented the design of vertical and transect of channel and relativewaterpower calculation.In the system the visual requirement of software was considered, the command and the database handle were availably packed, and the menu interface to the user was adopted. The system was of efficient, quick and expedient. Therefore it has great value of practice.更多还原
