| Abstract: | The hauling construction technology, as the main method for steel truss girder of railway overpass, has such advantages as being of economical, rapid, without interrupting the existing traffic etc. , especially when overpassing busy traffic road. Taking the hauling construction practice of an 80m span steel truss girder as an ex- ample, the design and calculation of the hauling construction have been introduced, which chould provide refer- ences for the similar engineering. |
