| Abstract: | Taking the design of Sanshan Bridge in Nanjing City as the study object,this paper describes the considerations of structural formation of the self-anchored deck arch bridge and makes a study of the influence of two critical factors of the prestressing tendons and rise-to-span ratio on the thrust of arch springs of the type of the bridge.In addition,the paper also presents the optimal design method for the prestressing tendons of the bridge.The results of testing in the filed prove that the design method as... |
