Abstract：Research purposes:The main bridge of Hutiaomen River Bridge，a constituent part of Guangzhou-Zhuhai Railway，is designed as a hybrid structure of continuous rigid-frame structure and truss-arch with three tubes. The bridge is a single line railway bridge，so the width of the bridge is narrow and the main span is long. The problems of the structure are transverse stability and later creep with long-span single line railway bridge. It intends to find a reasonable solution from the structure layout.
Research conclusions:It creatively adopts truss-arch with three tubes which is composed of external two parallel tubes and interior basket handle inclination of odd tube. External two parallel tubes are used to tension the suspenders and interior basket handle inclination of odd tube is used to strengthen the lateral stability of the structure. The structural components have clear division of labor and reasonable stress. The problem of transverse stability with long-span single line railway bridge is solved. The composite structure is actively to adjust the tension force of the suspenders. The distribution of internal force with dead load is optimised and the stress with beam between the top section and the bottom section is reduced. The problem of later creep with long-span single line railway bridge is solved. The bridge structure is characterized by arch structure of novel，great global rigidity and economic appearance. It will provide a useful reference and new ideas for the study of similar design of railway bridge.
