基于热力图的地铁车站变形可视化分析

Visualization Analysis of Metro Station Deformation Based on Thermodynamic Diagram

为了直观地展示地铁车站在施工过程中整体变形的实时分布情况,文章基于等高线生成算法,对变形监测点数据进行热力图可视化研究;基于某地铁车站的变形监测数据,针对地铁车站在施工过程中的地表沉降、桩(墙)体水平位移、支撑轴力等监测项目进行变形可视化分析。结果表明,采用热力图可视化分析方法对监测数据进行实时分析,得到了对应监测项目的变形实时分布情况,能更加形象、快速、直观地展示出地铁车站不同位置的宏观变形情况。这种基于热力图可视化进行监测变形分析的方法,丰富了施工变形分析的研判手段。

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 car⁃ried 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.
