The application of GIS in visualization of geotechnical data (SPT-Soil Properties): a case study in Eskisehir-Tepebaşı, Turkey

Abstract

Recently, three-dimensional visualization of soil characteristics has been widely used in geotechnical engineering applications. In this study, the 3-D visualization of Tepebaşı area soils, the province of Eskişehir, is prepared using SPT data, soil classes through Environmental Visualization System-Mining Visualization System (EVS-MVS) programs. Moreover, the local soil conditions were classified according to the Turkish Earthquake Code 2018 and digitized using Geographical Information Systems (GIS) and the data observed by the field and laboratory tests. The local soil conditions are observed utilizing the map classified according to the Turkish Earthquake Code 2018. By taking these 3D visuals and maps into consideration, it is determined that soil is alluvial. The ground water level is high, especially in the city center; the local soil type is ZD, ZE and ZF, according to the Turkish Earthquake Code (2018). Examination of the 3D visuals and maps reveal soil's the changing soil profile with a gradual gradation from fine grain soil (clayey and silty) at the surface; to coarse grain soil (sandy and gravelly). Therefore, the 3D visuals and maps established in the scope of this study may provide preliminary information to the researchers and pragmatists in the area.

“…Similarly, for factors involving distance calculations (linear factors), the Euclidean function was utilized. As for the geology data, since geology remains constant within small areas, resampling it to a 30 m cell size would not impact data accuracy (Civelekler, and Pekkan, 2022).…”

“…Geographic information systems (GIS) are important for decision-makers to better interpret and visualize events and data [26][27][28][29][30]. It is also said that GIS is an important technology for air pollution [31][32][33] and natural disaster studies [34][35][36].…”

“…Geological map of the study area is presented in Figure 2. This alluvial soil is divided into two as old alluvium and new alluvium by some researchers [17]. Some parts of the study area are located on the soil, which is geologically defined as new alluvium consisting of younger and loose material.…”
