成都地铁深基坑变形可视化研究

基于成都地铁车站深基坑的实测数据,建立该基坑的独立坐标系,并对基坑测斜数据进行处理,得到独立坐标系下基坑各个特征监测点Pi的三维坐标(Xi,Yi,Zi)及变形值Ci,组成监测点的4个参数(Xi,Yi,Zi,Ci)。利用Matlab对数据进行可视化处理,通过色阶变化可发现基坑各部分的变形特征。可视化分析方法较单数据分析方法更直观,且可进行整体分析,为基坑变形数据分析提供一种新的途径。

Research on Visualization of Deep Foundation Pit Deformation in Chengdu Subway

Based on the measured data of the deep foundation pit of Chengdu Metro Station,this paper establishes the independent coordinate system of the foundation pit and processes the pit monitoring data.The three-dimensional coordinates(Xi,Yi,Zi)of the characteristic monitoring pointsPiof the foundation pit in the independent coordinate system and the deformation amountCiare obtained,so that the monitoring points contain four parameters(Xi,Yi,Zi,Ci).The data is visualized by Matlab software,and the deformation characteristics of each part of the foundation pit can be found through the color gradation change.The visual analysis method is more intuitive than the single data analysis method,and can be analyzed as a whole,providing a new way for the analysis of the foundation pit deformation data.
