<p>Taking the partial cable-stayed bridge with main span of 248 meters which used on the railway coal corridor from western Inner Mongolia to central China as an example. the adaptability and particularity of partial cable-stayed bridge in the span range are analyzed based on structural static analysis theory. Pylon and girder rigid fixity, pier and beam separation system is applied, H- shaped bridge towers, the double cell concrete box girder and the monofilament epoxy coating prestress strand is used in this bridge. The results indicate that stay-cables contribution to the overall stiffness value of 33%. In order to improve the structure performance of the controlling area such as cross section, bridge tower adopt the high tower type system, depth-span ratio is determined to be 1/4.35, C60 high performance concrete is applied. The main pier bearing adopts double 190000 kN large tonnage steel spherical bearings because of the heavy dead loads and the heavy live loads, using the high-performance materials and Partial sealing technique to ensure the bearing durability, stability and long service life. The structure of the bridge meets the requirements of heavy haul railway according to the analysis.</p>
