Improvement of engineer properties of clay soils can be achieved by the action of the concentrated explosive charge or by applying a blasting method in the coherent soil. Detonation of the concentrated explosive charge in the clay soil generates a shock wave supported by the expanding explosion product that creates intense strong pore excess pressure and oscillations in the surrounding area of the explosive charge. In that case, the natural structure of the clay soil is destroyed, a significant increase in the borehole volume is achieved, the spherical cavity is generated, and in the adjacent area the clay soil is significantly compressed and its density increases. With the detonation of the generated shock wave in the soil, the released energy creates a strong pore excess pressure and intense vibrations in the surrounding area of explosive charge. During this process, the natural structure of the clay soil is destroyed, cavities are created near the explosive charge, and in the zone along the wall, there is an intense compression of clay soil with an increasing density. The efficiency rate of conducted blasting is a volume of the resulting expansion. The expansion volume and the compaction of the clay soil can be determined by field and laboratory research. For this purpose, the system of observation, measurement, and calculation of the shape and volume of the resulting cavity is being 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 coordinate calculations. This system represents the integration of RTK GNSS, Heavy Duty GeoVision Borehole Camera and Laser (EDS-C). For calculating the generated cavity and its volume at a certain depth of recording, an application "Bušotine" was created. Field researches and innovations in field data processing resulted in a sufficient amount of quality data that enabled the development of this type of application. The significance and contribution of the application "Bušotine" are reflected on the one hand in the use of open source technology, and secondly in commercial utility compatibility and the ability to connect to other systems through a series of interfaces. The added value of an application is achieved through the use of web technology, enabling secure login to the system from any computer, tablet, cell phone or other similar device connected to the Internet. All the information that users collect and enter into the system are immediately available to all remaining process parts. The concept and possibilities of the application in the technical field are innovativeness. Aside from the application's calculation of the coordinates and the generated cavity and its volume, the application gives a detailed graphical interpretation of the 2D and 3D view of the resulting cavity. Also, the compatibility of the application with other CAD tools will greatly contribute to a check and a more detailed 3D cavity view. The use of the standard field and laboratory methods will determine changes in the compressive strength, shear strength, density and elasticity modulus in the clay soil after blasting. This research will enable the determination the improvement of the soil properties depending on the detonation parameters, quantity, and type of explosives. Accordingly, with the determination of the influence of the above-mentioned blasting parameters on the shape and volume of the implemented extension in the doctoral dissertation, suggestions will be proposed for selecting the blasting parameters according to the required properties of the surrounding clay soil improved in accordance with the requirements for anchoring the concrete soil structure in geotechnical practice.
