The stress system of cable-stayed bridge and the setting mechanism of side-span auxiliary piers are set forth.Taking a steel-concrete composite cable-stayed bridge with a main span of 300 m in Jiangsu Province as the research background,six different constructing conditions are designed by using the indexes of stress amplitude of the girder,the displacement amplitude of the girder and the horizontal displacement amplitude of the main pylon.The calculation results under the different constructing conditions are analyzed and studied.The reasonable setting interval of auxiliary pier is given.
