  • Development of a 3-D design and measuring process for bridge engineering
Subject(s): Online resources: Bibl.nr: VTI P3021:2005-12Location: Abstract: The report documents the results of the "Intelligent bridge" project carried out 2001-2004. The aim was to develop the 3-D design and measurement process of concrete bridges. ln bridge engineering the management of geometry creates a basement and frame for successful execution of bridge design and construction. Superstructures of bridge must be accurately designed according to road geometry. The substructures needed for a bridge depend essentially on the terrain geometry of bridge site as well as ground features. The dimensions of bridges are often so large that construction works must inevitably be operated phased during a long time schedule. Therefore the creation and maintenance of a common and accurate coordinate system is an unique prerequisite to carry out different construction activities. The management of geo metric information throughout the total process is one of the most essential key tasks in the domain of bridge engineering. It is important to control information flows from early initial measurements to design phase deriving the optimal geometry for the bridge. Again, different site control models must be derived from the design models enabling also the comparisons between as built measurements and control models. Hence, the R&D efforts on to the improvement of the geometric management will be directed to one of the most important core of the total process in bridge engineering. The transition to this new 3-D process seems to be well-founded on account of the results of the project. Different technological and economic benefits were evaluated to be attained both in bridge design as well as in site measurements. New extrusion based design methods were developed for modeling the different parts of concrete bridges, ln future, it is also possible to complete 3-D geometry model with non-geometry information.
