This continuous box girder bridge design is divided into two aspects, and three of the medium span, both sides are 90m long, and the main span length 140m. So the length of the bridge is 600m. According to the mission requirements, the bridge is the main road in the suburbs, so the overall twoway six lane. Single box chamber fulcrum beam 8 meters high, span variable cross section, beam height of , deck wide 19m. Through 3,75m single lane width, paveme nt width of 2m, right shoulder , guardrail is . This design is mainly through the simulation of the whole construction process of the bridge, and the bridge, the static load, live load and internal force analysis and calculation. In, using the bridge construction simulation, the first step is partitioning the whole bridge unit according to the bearing capacity limit state and normal use limit state results software doctor bridge and pare the output, choose a larger value of the reinforcement calculation. According to the results, it is carried out. The input and construction of the steel beam are simulated and then the relevant provisions of the relevant provisions of the load, pre stress, etc.. After the bridge, the bridge, according to the relevant provisions of the public pre adjustment, the bridge deck pavement, and the calculation of the bridge deck and reinforcement calculation. Secondly, according to the bridge, the bridge upper structure is checked, and found support reaction, according to the bearing of the bearing selection of relevant specifications. Finally, the design of bridge pier foundation, to support the general use of steel beam to column connection.
