| Abstract: | This paper introduced above structure and construction plan of Dongping Waterway Bridge of Gui-Guang railway,analyzed the mechanic behavior of the main truss,deck system,longitudinal and transverse connections.In addition,the G11 joint which bears complicated forces was analyzed.This type of bridge is the first time in China,and compared with traditional steel truss arch,it overcomes the shortcoming such as long span in side and small stiffness. |
