【正文】 ditions and geological conditions on the line and station lines are related to the choice of the span, pillar layout and type selection and the anchor length of the division, Then in accordance with the relevant requirements of the design manual column in the table on the side of the gauge, pillar type, geology, such as installation of the corresponding figure number expressed. Highspeed catenary and the normalspeed catenary design or construction, have a lot of difference. Therefore, the technology which this design used does not make use of by the normalspeed catenary the same time, pay attention to all aspects of design considerations to enable the design of technical, economic, and aesthetic aspects of basic requirements to meet. In addition, late in the design, the paper touches the characteristics of catenary, discussed the mayor differences between the highspeed catenary and the normalspeed catenary, explained the key technology of the highspeed railway catenary construction to provide necessary reference and guidance.
