Digital Design Of Gravity Dam And Study Of Application

Some discussions with practice and application are deploied in the thesis , associating with the status of Hydroelectricity CAD application and the peculiarity of hydroelectricity building now. With Gravity dam as example , the thesis also combines the best new criterion of Gravity dam(DL 5180-1999).On the base of analysing and suming up some builded Gravity dams, the thesis gains mutual frame-shapes of Gravity dam. The frame-shapes are parted some independing frame picture-parts , and each of frame-part is digital analysed . Finally, the programmers are designed and opened out on the base of parameters. The mostly aims of the thesis are developed the Gravity Dam Parametrical Model System . The system can automatic cut open for model and can export model to the universal finite element analysis'software to calculate. Finally , the author discuss in the place drawing. The thesis has too much fact meaning for application of project.Base on the fact of hydroelectricity industry, AutoCAD is mainly tool of compute-aided design. So the author opens out the system of Gravity dam CAD in ObjectARX and VBA on the base of AutoCAD 2000.
