Abstract
A simplified method based on GIS combined with virtual reality modeling language (VRML) to achieve real time and fast 3D geological modeling is proposed. By calling the borehole rock and soil information stored in the GIS database, it is automatically created using spatial interpolation technology. The spatial interpolation technology is used to automatically create the side map of the model, and automatically output this information as a VRML script according to the standard format. The created model can be displayed independently without relying on the modeling software platform and can realize functions such as free rotation, flying, and zooming. Successfully developed a 3D geological modeling system based on the introduced design ideas, and used the system to achieve 3D geological modeling of a certain bridge site. This method has the characteristics of simple operation, fast modeling speed, less manual intervention, and visual interactive operation and can be used as an auxiliary decision-making method for engineering surveys.
