A Case Study on Integrated Modeling of Spatial Information of a Complex Geological Body

Abstract

Abstract To ensure the safety of project construction and reduce development costs, it is necessary to obtain a reasonable design before project initiation and to analyze and study geological information from multiple perspectives to achieve intuitive and effective project planning. Therefore, it is proposed to integrate above- and underground information to realize integrated spatial information expression. Generally, geological body model construction is based on drilling data, but most geological bodies are not simple layered structures, and complex geological phenomena usually occur, such as faults, lenses, and fissures. It is difficult to construct a high-quality geological body model with only limited drilling data. To fully consider existing geological information in complex geological areas with limited geological data information available, profile maps are considered in the modeling process. This article focuses on the geological model construction of a primary school in Shuicheng County, Guizhou Province, using the GoCAD platform. The Structure and Stratigraphy Workflow is applied in three-dimensional geological body structure model establishment, the stratum rock mass is outlined, and the complex geological structure (karst cave) is embedded into the geological surface. The model can be sliced at any angle to accomplish integrated spatial information expression of above- and underground building information combined with the same platform’s geological body to obtain engineering information and analyze future construction problems.
