基于GIS的建筑物沉降监测数据的三维可视化分析

3D Visibility Analysis of Building's Subsidence Survey Data Based on GIS

应用专业G IS软件MapInfo professional6.5的地图编辑、数据管理、空间分析和三维模拟等功能对北京科技大学2#学生公寓的沉降监测数据进行分析和处理,利用数字高程模型(DEM)建立建筑物的沉降变形专题图和三维模拟图。实践表明将GIS应用于建筑物沉降监测的工作中可以使沉降变形三维可视化,相比过去单纯依靠数据和报表进行描述更加直观、生动,有利于施工人员及时、有效地了解沉降变形信息,为工程施工和决策提供技术支持,也是将地理信息系统应用于土木工程日常施工与管理的一种有益尝试和探索。

Apply the basic functions of map edition, data management, spatial analysis and 3 D simulation of the GIS software MapInfo professional 6.5, analyze the subsidence survey data of 2# student＇s dormitory building of USTB. Establish buildingg subsidence distortion thematic chart and 3D simulation chart resorted to DEM. It is indicated that applying GIS to the work of buildingg subsidence survey can make the distortion survey 3D visual which is more intuitive and vivid compared with description only by data and table. It helps builders obtain subsidence information quickly and effectively, and provide technical support to the construction and decision - making. This paper is also an attempt and explore to GIS appliance in civil engineering＇s daily construction and management.
