[Abstract]:
The section of the highway from K1+600 to K4+700 is selected to design, which is
3.1 kilometers long. According to the route project of construction documents design
phase, the whole line adopts superhighway standard of two-way traffic and four
lanes. The designed velocity of the highway is 100 km/h, and the roadbed width is 26.0
m, The designed load of the bridge adopts highway-Ⅰ-grade,and the width of the bridge
is the same as the highway. The main contents of the project include the plain design,
the vertical section design, the cross section design, the protection engineering
design(the retaining wall of gravity ), the road surface design(Asphalt Concrete Pavement)
and bridge design。 Among them, the calculation and painting of flat design, vertical
section design, cross section design, the protection engineering design are designed
by handicraft .The design of road surface structure ,the calculation of the thickness
of the road surface and checking computations of the tensile stress adopt the design
system of the highway road surface structure--- HSP2000.And the bridge engineering adopts
bridge structure analysis software BSAS to design.
