Visual display method and system for pushing degree of steel truss girder based on digital twinning

The invention relates to a visual display method and system for the pushing degree of a steel truss girder based on digital twinning. The method comprises the steps that firstly, a three-dimensional model of a pushing construction environment of the steel truss girder bridge is built according to piers of the steel truss girder bridge, the three-dimensional terrain of a pushing site and temporarily built ancillary facilities; secondly, steel truss girder pushing displacement monitoring data are obtained in real time, and the pushing displacement monitoring data are transmitted to a cloud monitoring platform through the Internet of Things; the cloud monitoring platform analyzes and processes the steel truss girder pushing displacement monitoring data, and provides a data interface for a digital platform for visual display; and finally, a BIM model of the steel truss girder and the steel guide girder is established by the digital platform, and the current construction progress of the steel truss girder model is
