Abstract

The main objective of this study is to explore the application of 3D subsurface modelling as an advanced data visualization technique in geotechnical engineering prior to the designing and planning of civil engineering infrastructure. A detailed three-dimensional subsurface model of New City Phase-II, Wah Cantt, is created using a large dataset of bore logs, encompassing coordinates, depth measurements, elevation data, and lithology types of the study area. The combination of Geographic Information System (GIS) and Computer-Aided Design (CAD) technology has simplified the creation of this comprehensive three-dimensional model, resulting in a considerable advancement in the representation of complicated subsurface formations. The subsurface model highlighted the spatial distribution and lithological features of subsurface layers, indicating the presence of silty clay with varied stiffness at different depths. The validation using field data suggested a substantial spatial correlation, demonstrating the model's reliability. This study emphasizes the importance of 3D subsurface modelling in improving geotechnical site characterization, foundation design, hazard risk assessment, and effective land use planning. Future research will employ advanced imaging technologies, and data integration approaches to increase model accuracy and feasibility in a variety of geotechnical contexts.
