The main bridge of Kedu bridge in Meizhou of Guangdong province has an arch -beam composite bearing system,whose span is 2x80m and its arch axis adapts varied quadratic parabola.The calculation method and selection of arch axis,the selection and arrangement of suspender and tie bars in the design have been analyzed and discussed. Corresponding measures have been adopted to solve the problems encountered in the design process.In this paper,the related content of the design has been introduced,in order to provide reference for design of similar bridges.
