Three-dimensional Visualization of Expansive Soil Channel Slope Monitoring in the Middle Route of South-to-North Water Diversion Project

Abstract

Abstract The deformation of expansive soil canal slope in the middle route of South-to-North Water Transfer Project is obvious under the action of dry-wet cycles such as atmospheric rainfall and evaporation. By means of three-dimensional visualization, the deformation trend and characteristics of canal slope in three-dimensional on-line can provide more intuitive and clear basis for the stability evaluation and rapid disposal of canal slope. Based on the self-developed three-dimensional geographic information platform -3D GIS-Ark, this paper studies the three-dimensional visualization expression method of channel and safety monitoring information in the middle route of South-to-North Water Transfer Project, and realizes the three-dimensional model of Nanyang Expansive Soil Canal section, the visualization expression and early warning of monitoring equipment management and section monitoring information. The three-dimensional visualization results studied in this paper can provide visual decision support for engineering safety analysis, intelligent evaluation and early warning, and have significant application value in the field of engineering safety monitoring.
