ABSTRACT


  This design is Chenqingriver bridge two-stage constructional drawings design. Its central milestone is K57+482.10m, the clearance of width of bridge deck is 9+2×1.0m, highway grade is grade-two, auto load is highway-Ⅱand crowed load is 3.0KN/m2. Superstructure of the bridge uses 3×40 m prestressed concrete simply-supported T beam and substructure adopts two-columned pier , ribbed plate abutment and bored pile foundation.

  There are four components through out the design. The first part is hydrological computations including minimum net length determination of bridge span and minimum elevation of central bridge deck computation and scour depth computation; the second part is superstructure design, including confirming the size of cross sections, calculating the design forces of restraining sections and combining them according to The Criterion, estimating the amount of prestressed steels and arranging them, calculating the geometrical traits of cross sections of girders, calculating the loss of prestress, checking the carrying capacity of cross sections, check computations of the anticrack capacity of the structure and deformation in the ultimate state of normal use, and the stress of cross section respectively in the state of lasting load and in the state of temporary load; the third part is substructure design, including the drawing of size of pier and abutment ,checking computation of length of pile; the forth part is construction scheme design.Above all ,the major one is superstructure design.

  By design and checking computations, the design is reasonable.




Key words: Prestressed concrete;Simply- supported T beam;Two-columned pier;Ribbed plate abutment;Bored pile foundation.
