Abstract 2D underground models that reflect the physical, mechanical and structural properties of the geological units below the ground are called geotechnical cross-sections. In order to visualize these cross-sections, geotechnical engineers record the measurements obtained from vertical electrical sounding, seismic refraction or drilling methods. The visualization process is done by hand and it may vary depending on the researcher’s academic knowledge, intuition and drawing ability. Therefore, a visualization may be considered inaccurate by another researcher. However, geotechnical cross-sections should not vary according to a researcher’s perspective. For this reason, there is a need for an application that standardizes the process and has the ability to visualize cross-sections fast and in a practical way. For this purpose, we have developed a web-based visualization application that automatically generates geotechnical cross-sections. A fuzzy logic approach with dynamic rules has been applied to standardize the visualization process. In our experiments, hand-drawn cross-sections were compared to those that were generated by our application and the mean visualization accuracy of the system was calculated as 88.39%.

Introduction A geotechnical cross-section is a graphical underground model that provides information about the properties of underground strata of a region in the light of data obtained from seismic, vertical electrical sounding and drilling methods (Ghafoori et al. 2011). Geotechnical cross-sections are modeled by interpreting the values in more than one

data set without depending on the data of single method in an area (Demirci et al. 2017). In this respect, it differs from seismic and resistivity models (Dhamiry and Zouaghi 2019). Geotechnical cross-section analysis and modeling benefit engineers in many fields. For example, in the construction sector, the location on which the foundations of a building will be based are of vital importance (Tezcan et al. 2006; Uyanık and G¨ordesli 2013; Atat et al. 2013; Nayan et al. 2015; Adewoyin et al. 2017). If a tunnel is to be opened in a region, the soil or rock types of that region should be known and appropriate tools and techniques should be applied accordingly. The geotechnical cross-section is engaged at this
