In this paper , the optimum design of the outline of the rail girder for the gantry crane of the trashrack at power intake on right bank, Xiangjiaba Hydropower Project, is described.In view of the analysis on the construction methods and construction period of the girder, the cast-in-situ girder is changed to the precast one.The optimized rail girder is designed according to the structure of the com-posite one, reinforcement is arranged based on requirements of Design Code for Hydraulic Concrete Structures and the girder joint is trea-ted.Construction of the optimized girder is convenient, the construction period is shortened, and the construction safety is secured.This optimization paves a new way for the design of the rail girder for the gantry crane.
