On the basis of the brief introduction of the research and application of intelligent prestressed tension system in China, this paper introduces the composition of typical intelligent prestressed tension system, which mainly includes the application of post-tensioned beam, pre-tensioned beam, ground anchor cable and steel strand, etc. Then it Outlines the effective prestress measurement method based on magnetic flux technology, and finally describes the intelligent tension system Engineering application of unified and effective prestress measurement methods. Using the prestressed intelligent tensioning system in this paper, the tensioning construction, data recording and construction management of the prestressed beam can be carried out scientifically and normatively according to the preset program, the influence of manual intervention factors can be reduced, and the quality of prestressed tensioning construction can be effectively guaranteed.
