The Research & Development Of AutoSD Software For Aided Design Of Hydraulic Tunnel

In this paper, the features of hydraulic structures and processes of hydrotechnics design are particularly analyzed, expatiating the actuality and the developing trend of the software of hydrotechnics aided design. Emphases are given on the techniques of programming AutoSD software for aided design of hydraulic tunnel by utilizing the means of Automation ActiveX, illuminating the ways and the. means of development of hydrotechnics aided design software by using modern programming theories.Firstly, this paper has emphasized the essentiality and feasibility of computer aided design(CAD) for hydrotechnics design, analyzed the actuality and the disadvantages of nonce CAD software, forecasted the direction of the CAD softwares by combining the viewpoints of literatures. The author insists good CAD softwares for hydrotechnics design would be universal, interactive and systemic, and be easily handled, be expediently popularized.Secondly, this paper has introduced the CAD software for hydraulic tunnel, AutoSD. AutoSD is a compositive software for hydraulic tunnel aided design, with functions of route selection of tunnel, atress analyse and computation, exporting drawings and reports.AutoSD software is programmed by Visual Basic6.0, organized by event-driven methods. AutoSD software is composed of 4 modules: management of tunnel design processes, management of tunnel design data, computation and resultes output of tunnel design, and 20 sub-modules. This paper has recommended the sub-modulesof route selection, geology analyse, hydraulic computation, liner styles selection and liner stress calculation, which belongs to the module of computation of tunnel design.The research and development of AutoSD software has settled the problem of the combination of the design theories and drawing settings, the problem of design information and data management, the problem of harmony of artificial correct and program running, the problem of obtaining information from the original relief maps and geologic drawings, the problem of automatic exporting drawings and reports.AutoSD can work with AutoCAD and MSWord with jointless, so this paper particularly narrates the means of using Active X technique to call server programs(AutoCAD&MSWord) through client program(AutoSD).Finally, as a example, the author demostrates the design process of a hydraulic tunnel by using the CAD software AutoSD. The program displayed approving outcome, automatically exporting drawings and reports.Above all, during the research of the automatic of hydrotechnics designs, the author has successfully developed the CAD software AutoSD for hydraulic runnel design, and realized the function of immediate interpose among program and relief maps and the overall process computer aided function during the hydraulic tunnel design. The AutoSD software has achieved the purpose of the automatization of hydraulic tunnel design, has provided methods of the combination of hydrotechnics designs and projects environment, has lay the foundation to the development of the CAD softwares for hydrotechnics in the future.
