摘要: 基于3D GIS技术,结合一个具体的滑坡变形监测工程实例,采用不规则三角网和等高线构建了滑坡体三维模型;对于mm级的变形,通过放大和橡皮筋动画技术,在三维空间再现了滑坡的微观变形过程。

Abstract: The deforming of landslides usually expressed in horizontal and vertical direction separately.Based on the X,Y,Z coordinates from a real monitoring project.A method is proposed to build 3D model of landslides by constructing triangulated irregular network(TIN) and extruding contour lines.The tiny movement of monitoring points becomes visible by zooming movement vectors,and the whole landslide deforming was replayed using rubber-band animation techniques.
