A multi - approach geophysical estimation of soil dynamic properties in settlements: a case study in Güzelbahçe- İzmir (Western Anatolia). For a more detailed graphical interpretation, an application was developed, which calculates the coordinates, shape and volumes of the formed spherical cavity. The main objective of the study was to determine the resulting shapes and volume of the occurred cavities. The results obtained in this way, showed that there was an increase in the stiffness of the surrounding clay soil after blasting. Shear wave velocities (V S ) were calculated using MASW method to evaluate the dynamic properties of the clay soil along the in-situ profiles. The Multichannel Analysis of Surface Waves (MASW) measurement method was also used during the study. The GNSS measurement method was instrumental for obtaining the coordinates of the borehole. The expanded spherical cavity, formed after the blasting of the explosive charge in the bottom of the borehole, was measured by a depth camera-laser system. For this purpose, the integration of the Global Navigation Satellite System (GNSS) method was applied in addition to the depth camera and the laser, to determine the resulting spherical cavity. A depth camera was used to record the spherical cavity which occurred during blasting in clay soil. ![]()
