| Abstract: | The article compares and selects the technology and the economy of the bridge scheme with about 100-m span from the angle of the whole line. The article puts forward that (1) the continuous beam has the side span, and the area of the main span is large; (2) the height of the continuous beam is large, and the area of the bridge in the whole line is large under the condition of the equal longitudinal slope; (3) the different types of the bridges are relatively to the critical point of the technical and econom... |
