The center station number of this bridge is K190+165.38, span 126.47 meters, design load roadⅡThe level, the crowd load 3.0KN/㎡, the bridge floor extends only: - 7+2×1.0, upside uses prestressed concrete simple support T Liang only, the lateral section constitutes by 4 piece of Liang, the longitudinal span 40.5 meters, 3 step. The bridge floor transversal grade 1.5%, the bridge floor lengthwise grade 0.5%, the flooring uses the cement concrete. Lower part uses the light platform, the drill hole irrigation pile foundation.
Entire design process including four partial contents: Hydrology computation, superstructure design, substructure design, construction technological design. Had determined the bridge span with questions and so on minute hole, has drawn up upside the size, has completed the endogenic force computation, upside the reinforcing bars, computation work and so on section checking calculation, also have simultaneously carried on the bridge platform foundation computation and the checking calculation. Key for superstructure endogenic force computation and reinforcing bars computation, section checking calculation
The computation indicated that each checking calculation meets the requirement, the design proposal is reasonable.
