The Construction Control In The Trestle Construction Of Reinforced Concrete Arch Bridge And Analysis Of Spandrel Construction Combined Action

As a traditional form of bridges, reinforced concrete arch bridge represents a majorcomponent of bridges built, and is still competitive in a period time of future in themountainous areas and other regions appropriate to build arch bridge. To ensure thesuccessful closure of the bridge, and make sure that the axis shape and the internal force ofthe bridge accord with the design request, construction control is of great importance duringthe bridge construction.This article takes some reinforced concrete arch bridge as background. The writer usesMIDAS/Civil software to create a finite element model of the process of the bridgeconstruction, analysing the main arch stress and arch axis linear control section on theconstruction stage which is compared with the measured values. This articles gives a specialanalysis on the coaction of the building on the arch, and compare four different methods inthe process of construction. Finally this paper gives the suggestion.The achievements of this paper will influence the future research in the same aspect.
