The form such as the box in section, T-shaped.In construction, girder segmented construction figure of the unit in charge of construction according to designing institute's offer, using cantilever
Pouring construction engineering method construction girder segment, finally closes up.
At present, bridge BIM Top-Down Designs are realized in the design phase and go out the case of figure almost without.Therefore, unit in charge of construction
In the case where the BIM models of designing institute cannot be obtained, it is common practice that with Autodesk Revit softwares, carried according to designing institute
The CAD blueprint reverse modelings of confession, complete continuous beam cantilever and pour BIM modeling works and subsequent applications.And girder traditional at present
There are problems with for three-dimensional modeling process：
1st, girder modeling plane positioning uses two dimensional surface design route as base map, and elevation location is high using main beam design
Degree, when next similar project occurs, the change that bridge route information occurs causes main beam structure positioning to be difficult to parameterize
Adaptive adjustment, this non-automated causes model modification difficult, once therefore model need change to model again, imitate
Rate is relatively low.
2nd, girder modeling is not according to design segmentation modeling, and the model for causing to establish is in cantilever engineering method construction simulation and segmentation
Construction requirement is unsatisfactory on the point of applications such as quantities statistics, can not accurate guiding construction.
3rd, girder variable cross-section number of fragments is more, and cross section parameters change is more, also divides or so width, causes modeling efficiency very low.
4th, the beam section of multi-quantity splices location difficulty manually, and gap is more, and mistake is more, it is impossible to meets modeling accuracy and construction
Site requirement.
