GIS-based 3D dynamic visualization of simulated complex construction process

Significant advances have been made in the field of complex construction process simulation. However, no convenient graphical support tools exist that can depict the construction process in 3D dynamically. In this paper, with the application of Geographic Information System (GIS) and visualization technology, a GIS-based 3D dynamic demonstration system for complex construction process is developed. The three-dimensional vector model, graphic data structure and animation of construction process are given. Based on these, a 3D animation of the whole construction process is carried out and the construction process is presented visually. Finally, this system is applied to a large-scale underground structure group construction. The results show that visualization of simulated construction process has excellent intuition and provides abundant information for engineering decision-making.
