geophysical methods are also used significantly. It should be noted that the in-well seismic method is one of the methods that is most used in Structural studies. In soil model analysis, seismic studies and geophysical excavations are of special importance because with these studies the speed of seismic waves transmission Are measured directly by the layers of the earth and their dynamic modulus is estimated. The most important quantitative parameter to determine the type of soil is the velocity of the shear waves. To estimate the velocity of the waves, they can be used if there are enough wells that can be harvested inside the well.
Geophysical methods are in the group of dynamic methods; Because the deformation properties of materials depend on the speed of propagation of elastic waves in materials. Today, the application of geophysical methods, especially seismic methods in geotechnical studies is increasing The purpose of this study is to separate the subsurface layers in terms of differences in shear and compressive wave velocities and also to determine the dynamic parameters for each layer due to their effective role in geotechnical studies and foundation design
