3D GIS BASED LONG-DISTANCE PROJECT CONSTRUCTION PROGRESS VISUALIZATION

The construction progress of a long-distance project can generally be reflected by the percentage of the total length of the segmented project on the main line to the total length of the line. However, the way to express the construction progress based on the percentage is not intuitive enough and it is difficult to reflect the segmented project. Insufficient progress differences. This paper proposes a 3DGIS-based visualization method of long-distance project construction progress. Through regular project construction progress report, the completed line can be automatically generated. At the same time, the overall and local construction progress can be visually expressed through the superimposed display with the main line of the project and the three-dimensional terrain. The experiment combined with the engineering example of the Kunming section of Central Yunnan Water Diversion Project shows the visualization effect of the excavation progress of the water conveyance tunnel, and verifies the effectiveness of the method in this paper.
