Three Dimensional Modeling and Visualization Information Management of Geotechnical Engineering Investigation Sites

Based on several kinds of geotechnical engineering information obtained from multiple sources and different structures， such as drilling hole detection， standard penetration test， topographic surveying etc.， a series of specific methods for data preprocessing， integral modeling， 3D visualization and information management of the engineering sites were intensively inverstigated. Based on these methods， a software was developed， by which the stereo space of a geotechnical engineering site， including spatial objects such as topography， buildings， boreholes， stratum， groundwater etc.， can be integrally modeled and visualized with three dimensional models. These 3D models can facilitate functions such as attribute query， information updating and section analysis. The 3D integral modeling software was proposed as a new pattern of geotechnical engineering report beyond traditional 2D report. The software has been applied to several geotechnical projects， whose results demonstrate that the stereo space model of a geotechnical engineering site can be automatically and conveniently reconstructed. The 3D integral modeling and visualization methodology presented contribute a lot to 3D information technology development of geotechnical engineering.
