Geographical Information System (GIS) is a powerful tool for representing huge data and producing an actual visualization of subsurface information and parameters in the form of 3D scenes that can be used by the geotechnical engineers in the design of footing and foundation. This paper focuses on producing digital geotechnical maps for the main geotechnical parameters that can be used in the preliminary design stage. Considerable data of 164 borehole logs presenting a 17,000 km 2 (i.e. Wasit province, south of Baghdad, Iraq) are collected, analyzed, tabulated in an excel sheet, and used as input data to create the digital maps. The studied parameters are bearing capacity, shear strength, coefficient of consolidation, compressibility parameters, and groundwater levels. The results show that the GIS technique is a great tool to visualize the geotechnical parameters that can be easily used directly in the assessment of the site investigation reports and even in the foundation design. The digital values of the bearing capacities, shear strength, and compressibility parameters are clearly visualized and accurately replicate the soil layers of the study area. However, other geotechnical parameters are needed to further consider it in more digital maps.

“…Researches relating using GIS to study the spatial variability of different soil properties have increased in the recent past years (Al-Mamoori et al, 2019b; Mohammed, Yahya and Ahmed, 2012). Four case studies investigated by (Hellawell et al, 2001) considering the use of GIS in analyzing geotechnical data for small scale projects. The first case included an archaeological desk study where GIS used to create a model for possible ground conditions to identify possible sedimentological features, the resulted models were numerically correct but with no real physical meaning.…”

Geotechnical engineering like any other engineering field has to develop and cope with new technologies. This article intends to investigate the spatial relationships between soil’s liquid limit (LL), plasticity index (PI) and Liquidity index (LI) for particular zones of Sulaymaniyah City. The main objective is to study the ability to produce digital soil maps for the study area and determine regions of high expansive soil. Inverse Distance Weighting (IDW) interpolation tool within the GIS (Geographic Information System) program was used to produce the maps. Data from 592 boreholes for LL and PI and 245 boreholes for LI were used for this study. Layers were allocated into three depth ranges (1 to 2, 2 to 4 and 4 to 6) m. A total of 1396 observations were used for producing the maps for both LL and PI, and 371 data for LI. Based on the results, the IDW method gives reasonable predictions depending on the results of R2 and RMSE. The results also showed that the study area has relatively large zones of high expansive soil that must be taken into considerations before performing any construction activity. These maps are essential for helping geotechnical engineers in making decisions and visualizing soils’ behaviors.

“…In GIS applications the geotechnical data are usually presented through thematic layers (Oloufa et al, 1992;Adams et al, 1993;Camp & Brown, 1993;Oloufa et al, 1994;Giles, 1994;Nathanail & Rosenbaum, 1998;Kimmance et al, 1999;Suwanwiwattana et al, 2001;Hellawell et al, 2001). Construction of such thematic layers needs queries based on a soil layer catalogue, like "select some PARAMETERS from some LAYERS, in the SCOPE of " to the database.…”

“…GIS not only provides a sophisticated spatial platform to handle complex spatial analysis, it also integrates the data management, analysis, and visualization functions that are typically performed independently and bridges the traditional "islands of automation", it automates many time-consuming tasks and reduces manhours in searching and retrieving information (Hellawell et al, 2001). The engineer can thus focus on using the data efficiently rather than spending great effort in just Figure 1-1 Example ofSD-GIS visualization of proposed tunnel alignment (after Ozmutlu & Hack, 2001) In using GIS for geotechnical data management, various degrees of customization of the geotechnical databases are normally needed.…”

Development of a 3D GIS database model for geotechnical analysis incorporating geostatistics

The application of 3D GIS and geostatistical tools in geotechnical fields enables geotechnical engineers to think spatially and make decision wisely. To support the 3D GIS applications, geotechnical data need to be managed based on their spatial components. The objective of this study is to develop a new geotechnical database model supporting the spatial analysis requirement of a 3D GIS. The result of this study will provide a foundation for the future development of a 3D GIS geotechnical database for Singapore Island. A data requirement analysis has been conducted and based on the data requirements the new geotechnical database model is developed as a hybrid database model inheriting the advantage of existing geotechnical and geological models. The developed geotechnical database model combines the rational worldview of NADM model (North American Geologic-map Data Model), the rigorous data structure of the AGS format, and the flexibility of the XML schema. The proposed geotechnical database model highlights the existence of different interpolation results based on the same entities by decoupling the geotechnical test data from the stratigraphy schema. It enables the geotechnical test data to be fitted into various stratigraphy schemas without any constraints. To handle the subsurface stratigraphy data, an XML schema is developed for the hybrid database model. Using the XML support from the database industry, the complex relationships interpolated for different soil subsurface can be stored in an XML database and retrieved for reuse. Rather than breaking the stratigraphy information into different segments just for storage purposes without any geotechnical meanings, XML database can manage stratigraphy data as an integrated unit. Meanwhile, an XML schema for the variogram model is also proposed. By taking advantage of an XML database, the variogram for soil properties can be efficiently viii
