Collaborative 3D geological modeling analysis based on multi-source data standard

A multi-source data standard must be established to reconcile all available geological data such as borehole data, geological mapping data, and rock property data for building a reliable 3D geological model. In addition, a methodology that considers various available data must be developed to provide accurate results that are easy to interpret and convenient for post-modeling analysis. This paper presents a collaborative analysis approach for geological body modeling using multi-source geological data and interpolation theories in different stages and at different places. This approach aims to provide a detailed and comprehensive description and analysis of data, with emphasis on processing flow. The proposed approach contains three major components: establishment of geological databases based on the multi-source data standard to incorporate borehole, geological mapping and rock property data; Combined Kriging interpolation method for data processing; geological algorithms to build, visualize, and post-analyze the 3D geological model. The model integrates multi-source information and is a representative of the geological context. The proposed method is validated by applying it to the Ma-luan mountain tunnel project in Guangdong province, China.
