Abstract: In order to show the real-time distribution of the overall deformation of metro station during construc? tion, a visualization study on the data of the monitoring points is conducted based on thermodynamic diagram. In light of the deformation monitoring data of certain metro station, a visualization analysis on the deformation is carried out from aspects of ground surface settlement, horizontal displacement of the pile(wall) and the axial force of support. The results show that the real-time deformation distribution can be obtained by a real-time visualization analysis on the monitoring data based on thermodynamic diagram, which can present the macroscopic deformation condition at different positions more vividly, rapidly and visually.
