| 摘 要： | 针对现代大型工程变形监测手段丰富、监测点数目较多、变形可视化困难等特点,提出了以Midas GTS为平台,利用地形数据和监测点、特征点空间数据进行3维建模,通过对模型的拓扑变换和任意剖切,实现了对各类变形监测点变形量的可视化表达。以某隧道为实例证明该方法操作简便、表现直观,具有较强的实用性和有效性。

| Abstract: | In the light of the rich means of deformation monitoring, large number of monitoring points, difficulties of deformation visu- alization and so on in modern large -scale project, this paper builds 3D model using topographic data and monitor points and feature points spatial data and taking Midas GTS as platform, realizes the visualization of deformation value of various kinds of deformation mo- nitor points through model topologic changes and cutting. Taking a certain tunnel as an example, it is proved that this method is simple in operation, intuitive in expression, and is applicable and effective. |
