摘　　要：以某大坝蓄水期间的沉降数据为例,应用GIS专业软件中的空间分析和三维分析模块,对观测数据进行综合处理和分析,利用TIN模型建立多期大坝沉降三维模拟图,并和其他监测指标进行对比分析。结果表明:通过GIS软件生成的沉降专题地图和统计图表比传统方法更快捷、简单、准确,信息量更丰富;沉降三维模拟图更直观、生动、逼真,可及时、有效地将沉降信息和变形情况反映给项目决策者和施工人员以提高作业效率和精度,从而为整个工程提供技术支持和决策依据,是一种快速、准确表达沉降观测成果的有效方法。The spatial analysis and 3-D analysis modules in GIS software were employed to analyze the monitoring data of dam settlement during impoundment.In addition,3-D simulation graphs of the dam settlement in different periods plotted by TIN model were compared with other monitoring indexes.It＇s revealed that the settlement thematic maps and statistical charts and diagrams are more rapidly and conveniently generated,and contain more information with more accuracy than those by traditional methods.The intuitive and vivid 3-D simulation graphs of the settlement provide technical support for the whole project by informing decision-makers and engineers the latest settlement and deformation situation.In conclusion,it＇s rapid and accurate in reflecting the settlement monitoring results.
