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 …………………… |
