     GQJS( Bridge Structure Design System abbreviated as GQJS according to the Chinese phonetic alphabet )had been developed by the combined efforts of many experts in the Ministry of Communications. The predecessor of GQJS is GQZJ (Bridge Compositive Program abbreviated as GQZJ according to the Chinese phonetic alphabet ).GQZJ had been applied tentatively since 1978 and passed the technical appraisal by the Chief Bureau of Highway of the Ministry of Communications in 1980. During the last 20 years of spread and application of the program ……………………
 

   With the rush of highway bridges, the demand for bridge test increased evidently. On the base of GQJS and JFDJ, we have developed QLJC, a new system special for bridge test analysis. The main functions of QLJC list as follows. 1. Read the data file of GQJS and build spatial model with the basic spatial data; 2. Record project of bridge test and output project drawing; 3. Record the position of observation points and observe the distribution of all the observation points; 4. Analyze the test efficiency of every ……………………

 

     This system is one of the achievements of "Key Technology Research & Development of Humen Suspension Bridge's Superstructure Construction" commissioned by the Ministry of Communications, including the research of construction control and survey of superstructure and the research program for steel box girder segment setting and fixing . SBCC is specially used in suspension bridge construction calculation and can be used to analyze the initial position of suspension construction, decide working length of main cable or suspenders, decide cable's initial position in the unload state. And it also can be used for real-time tracing and analysis during the course of suspension……………………

 

     This system is mainly used for building three-dimension model of bridge structure including beam bridge, arch bridge, cable-stayed bridge and suspension bridge. The superstructure includes hollow slab, T-shaped beam or I-shaped beam , one cell box beam , flat hollow box beam , three cells box beam , steel box beam and combined beam with steel truss and concrete slab, the infrastructure includes U-shaped abutment, light type abutment, solid pier, thin wall pier, column pier, tower pier and anchorage and foundation includes spread foundation and pile foundation. The bridge model ……………………

 

     This system is mainly used to draw bridge layout, including elevation, plane, transect and table of design parameters 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 ……………………
