Accurate ground characterization is essential in geotechnical engineering, as it influences the safety and feasibility of construction and mining projects. Today, the digitization of geotechnical data and the use of technological platforms have improved efficiency and accuracy in subsurface modeling. This article explores the process of building a Digital Ground Model (DGM), detailing key steps in data collection, organization, characterization, and subsurface modeling. Finally, it highlights the role of specialized tools in optimizing these processes, with a focus on advanced solutions that have revolutionized the industry.
The development of digital ground models has transformed geotechnics, enabling a more precise understanding of the subsurface and reducing risks associated with geotechnical uncertainties. The integration of advanced technologies has optimized this process by providing centralized platforms for managing geotechnical data. This article discusses the key methodologies for constructing a digital ground model and emphasizes the benefits of its implementation in engineering projects.
Data Collection and Centralized Management
The first step in constructing a DGM is integrating geotechnical data from various sources:
Borehole logs and in situ and laboratory tests.
Historical and public information combined with recent data.
Centralized data management to facilitate access and analysis.
Proper structuring and management of this data are fundamental to ensuring the reliability of the geotechnical model.
Data Transformation: From Layers to Geotechnical Units
Once the data is collected, it must be transformed into a structured model. This process includes:
Identification of geotechnical layers from borehole logs and tests.
Grouping of layers into geological and geotechnical units, providing a coherent interpretation of the subsurface.
This organization facilitates the understanding of subsurface structure and lays the foundation for precise modeling.
Ground Characterization
Geotechnical characterization is a fundamental step in defining the mechanical properties of the ground. The use of analysis and automation technologies allows for:
Automatic calculation of geotechnical parameters, minimizing errors and improving consistency in interpretation.
Assignment of physical and mechanical properties to each geotechnical unit based on laboratory and field tests.
This approach ensures that subsurface models are accurate and representative of real conditions.
Digital Ground Model Generation
Once geotechnical units are characterized, the digital ground model is generated, which involves:
Advanced visualization, including the creation of detailed cross-sections.
Integration of the model into geotechnical analysis software, facilitating simulations and stability studies.
Digital solutions provide a clear and accurate representation of the ground, improving decision-making and optimizing foundation and structural designs.
