The Prestressed Track Beam Testing Technology of Shanghai Electromagnetic Levitation Train

Abstract

Shanghai electromagnetic levitation train (maglev) is the first one that is constructed and operated commercially in the world. Many technological problems have to be tackled during its construction, and the most difficult problem in the civil engineering part is the making of prestressed track beam. It requires high precision because of its special function. The stretching control of the pre-tensioning force and the post-tensioning force in the making of prestressed track beam is most important during the construction. This paper introduces and analyses the technical features of vibrating wire sensors as well as the development, the research and the application of force sensor for pulling force measurement of anchor cable.
