| Abstract: | This paper introduces the structural design of large span steel support in arch bridges with the calculation of internal forces and displacement of military arch support in vertical swiveling stages and concrete-casting stages,and also discusses the constructional process of semi-arched military beams support in Shiyanghe Bridge with the cooperation of pulley block and hoist,which enlarges the application of 64-type military beams.With the experience accumulated in the Shiyanghe Bridge,it also states the superiorities of the method of trestle construction used over reservoir,deep stream or valley. |
