Research And Design Of CAD System Of Channel Diversion--CAD For Construction Diversion

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.
