Abstract:This bridge project locates in Ding"an River section of the Hainan Hengxian Expressway where diversified restrictive factors, such as on-site gold mines, hydropower station, and hydrology condition, contribute to the difficulty in design stage and construction process. On this condition, the bridge is modified to align along the riverbank and cross the river multiple times, resulting in the noticeable differences from conventional bridges in terms of overall scheme, pier layout, hydrological calculation, and structural calculation. In this paper, the focal points both in conceptual and detailed design stages, detailed structural design of curved continuous rigid frame, and overall bridge structural calculation would be thoroughly discussed, providing a reference for the design of similar bridges.
