Abstract: In order to arrange a traffic bridge on the overflow surface hole of an arch dam of a hydropower station, it is necessary to set a widened corbel structure on the downstream side of the overflow surface hole gate pier, with a cantilever of 4.08 m on the downstream side, a height of 6.18 m at the root of the corbel and a plane width of 0.94 ~ 1.40 m. Combined with the current code and the actual situation of the project, this paper discusses the design of the widened corbel structure.
