“…In order to define 3D coordinates of boreholes (MB1 to MB8, MB13 to MB45 and PMB1 to PMB6), a RTK GNSS method based on CROPOS (CROatian POsitioning System) was used. The positioned boreholes are shown in Figure 3 (Težak, 2018;Težak et al, 2018;Težak et al, 2019).…”

“…Real-Time Kinematic (RTK) is a method where relative coordinates of an unknown point, in respect to the known one, are determined a moment after placing the rover on that point. The only limitation of the method is the distance range of radio connection which is resolved by implementing VRS (virtual reference stations) in CROPOS ( Figure 4) (Pribičević and Medak, 2003;Težak et al, 2018). Preceding to blasting was the measurements of characteristic field points to make up a geodetic map.…”

“…The construction of the borehole explosive loading is shown in Figure 10a. Figure 10b shows the moment of activation of the explosive charge, and Figure 10c shows a schematic representation of the resulting spherical cavity (Težak, 2018;Težak et al, 2018;Težak et al, 2019).

“…During the research, it was necessary to determine the shape and calculate the volume of the formed cavity after activating the explosive charge at a certain depth of a 131 mm diameter borehole (Mesec et al, 2015;Težak, 2018;Težak et al, 2018).…”

“…For this purpose, a system for observation, measuring and calculating the shape and volume of the resulting cavities was designed and developed. The system includes an instrumental and programming part, where a designed application enables detailed graphical interpretation of the cavity in 2D and 3D views, along with the borehole coordinates and resulting cavity volume calculations (Težak, 2018;Težak et al, 2018;Težak et al, 2019).…”

Blasting in clay soil in the field of anchoring and foundation of objects and structures has its benefits in construction and geotechnical practice. The foundations of the method lay in the fact that a shock wave is generated when the explosive charge is detonated. The shock wave, with high pressure at the wavefront, causes the natural structure of the clay soil to be destroyed, and a spherical expansion in the clay mass is formed. The presented research is focused on determining the shape and volume of the resulting expansion in test blasts performed with several types of explosives. An application named Borehole was developed to determine the resulting spherical expansion formed after the detonation of an explosive charge with the integration of the GNSS method of measurement, depth camera, and laser. The application Borehole calculates expansion volume based on the coordinates obtained with the GNSS and the laser-obtained distance of the formed expansion and provides a graphical interpretation in 2D and 3D views. Additionally, when developing the application Borehole, compatibility with CAD tools was considered, primarily for better verification and a more detailed graphical interpretation of 3D views. The developed method allows for simple determination of the volume and dimension of the spherical expansion in clay soil with acceptable accuracy for the design and building of geotechnical structures constructed above and underground.
