ten
This design is a (64 ＋ 2 × 113+64) m continuous beam bridge of expressway. The bridge in this design is a single room, three lane, four span highway continuous beam bridge, with a deck width of 12.75m and a bottom width of 7m. The beam height at the support is 7m, and that at the middle of the span is 3m, which is changed by 1.6 times of parabola; The base plate thickness at the support is 0.8m, and the midspan is 0.4m, with linear change; The web thickness is 0.7m at the support and 0.4m at the midspan, with linear change. The bridge axis is a straight line, with a cross slope of 2% and no longitudinal slope. The design load is highway Class I.
