| Abstract: | The Dina River Bridge in Guizhou is a deck arch bridge with the 120m span.Adopting the regular steel truss arch centering to place on site,the arch centering of this bridge is of the longest span erected with cantilever methods in Guizhou.Based on the engineering background of the Dina River Bridge,this paper introduces the application of the regular steel truss arch centering in placing on site during the construction.Through the computation of bearing capacity and whole stability in the process of arch centering construction,the construction scheme is checked and optimized.It provides some value for practical operation to the design and computation of similar bridge construction schemes. |
