Research purposes. Maglev train runs above the track and it runs quickly, safely and cozily. It generates low yawp, no wheel - rail friction, no pollution, so it has a great future and must be a new kind of important vehicle in 21century. The following paper describes the design theory of routine conductive maglev train pier bearing structure. Research methods： Upper support structure is analyzed as a gate -style frame. Elastic foundation beam theory is applied to analyze inner force and deformation in bottom beam. Research results.Contrapose maglev engineering, the article describes design load, calculate model, calculate pattern, structure calculate methods and structure design about the primary structure. The theory has adopted in a number of project experiments. Research conclusions： The theory and structure design method is reasonable and credible by project experiments and function practices for four years, which can run suspended and be popularized greatly.
