3、First, people prepared to make girders then hung them to be a continous bridge, and they adopted the same hight of changing section box girder of which the span is twenty-five meters, and the total bridge is divided into 6 spans with the whole lenth of 150 meters.There are seven chapters in the dire

4、ction. The first chapter is sketch, its about the pattern and dimension of bridge. The second is about the internal force calculating,including dead load、living load internal force、temperature and abutment subsided sequence internal force and compose load.The third is about the estimate and arrange

5、of the reinforced steel. The fourth, loss estimating.The fifth, calculate the intenal foce after distributing the steel .The sixth, check of strength.
