Abstract


Computer-aided design (CAD) technology in the field of bridge engineering engineers freed from many repeated heavy physical , mental , greatly improving the efficiency of labor , making the traditional means of bridge design , design methods produce a significant change , very earth to promote the technological progress of the bridge industry , one of the bridge Surveying the main symbol of the modern . CAD technology has made ??great contributions to the development of civil engineering , However, with the rapid development of computer software and hardware engineers to bridge CAD software requirements . For the bridge CAD technology application status and the increasing development of software technology , the technology of the bridge CAD software development system , the main contents include : the limitations of existing software ; modern software development technology in the the bridge CAD software applications ; integration the necessity and feasibility of bridges CAD system ; integrated bridge CAD system composition and architecture . Detailed study of the core database system and graphics system supported the bridge CAD system development techniques , proposed in the near future to ACCESS and AutoCAD as the core database and graphics support system . As the practice of the above theory , the paper attempts to use the ACCESS database and VBA tools continuous beam bridge CAD system to develop an integrated database system data organization and management of bridge software , database connectivity through DAO method , easily read and stored data . Combined with the actual situation of the system , this paper VBA development tools , using OLE AutoCAD secondary development to achieve a graphical query system pre-processing functions data support . These studies , for the development of integrated bridge CAD system theoretically made ??better explore , and from the practice given , as a further development of the system has laid a good foundation .
