Research conclusions：In the course of high-grade railway construction organization design, the more attention should be paid to combining the construction organization with the plans of construction schedule, the location and scale of laying rail, the beam construction, the location and scale of fabricating beam and materials supply. For defining the engineering cos,t the focuses should be made on the technical and economic comparisons of the track and bridge construction plans, earth-borrowing (stone) plan and infrastructure construction plans so as to correctly reflect the requirements of the design and construction.
