ty limit state. Among them, the upper structure of the main reference for bridge specifications with relevant examples. Using hinged plate method and the lever principle method to solve the transverse distribution coefficient. And relevant reference example for grouping hollow slab, the influence line of transverse distribution of the check, then the lateral distribution coefficient.The main content of this design includes the design and calculation of hollow plate, points pleted the geometry design, computing binations, steel bar configuration and checking calculation of prestressed damage calculation, persistent and transient state stress check and so on specific projects, each part has engineering calculation. Key words : prestressing force ; slab bridge ; Specification ; Influence line
