Taking uncertainty analysis for 3D geological structural models as the study subject, this project starts from constructing the mapping functions between 3D spatial errors and geological attribute probabilities. Error suites of triangles are constructed by the statisitcal simulation method to describe the multiple error impacts on triangle irrgular network. The theoretical study about uncertainty measurements for 3D geological structural model will be carried out based on vector parameters. Also, key factors that influence the uncertainty distributions in 3D geological structural models and the corresponding characteristics will be discussed with the help of vector parameters. This project will solve problems of quantitaive analysis and visualization of uncertainties in 3D geological structural model and will reveal the impacts caused by uncertainties that exist in raw data on the final 3D models. This research is aiming to break through the bottleneck of theoretical method of uncertainties analysis and to provide theoretical models and techniques for quality measurement and error correction for 3D geological models.
