This system is mainly used to draw bridge layout, including elevation, plane, transect and table of design parameter etc. The superstructure may be girder, arch, cable-stayed and suspension. The infrastructure may be U-shaped abutment, light type abutment, solid pier, thin wall pier, column pier. The foundation may be spread foundation and pile foundation etc. The bridge layout includes vertical curve, plane curve, abutment gores, ground layer, geology histogram, water level and structure dimension. This system is a convenient drawing tool for feasibility research, initial design, constructional drawing design of bridge project. This system is characteristic of user-friendly interface, convenient operation, technical advancement and strong practicability. With the modeling based on AutoCAD R14, the user can preview three-dimensional effect directly in environment of Windows and expand the database of structure parameter freely. The system is one of the achievements of the key problem of national science and technology research and development projects: National Main Trunk Line Design Integration System Development. It has passed the technical appraisal organized by the Ministry of Communications and was deemed to have reached the world advanced level in terms of system development technology.
