Abstract
This study, it is aimed to determine how soil parameters affect mass movement. The study area was carried out in the Şirinköy District of Merkezefendi District of Denizli. As a basis for the prevention of mass movements; Geophysical methods are of great importance in terms of determining and monitoring the properties of the sliding forces by determining the ground conditions in the region. For this reason, in this study, the characteristics of the mass movement were determined by determining the soil properties of the study area by using the seismic multi-channel surface wave (MASW) method, which is one of the geophysical methods. With the MASW method, it was determined that the seismic velocities of the area were lower than 910 m/s. As a result of the MASW studies carried out in the study area, the ground class is ZC according to the 2018 earthquake regulations; Very tight sand, gravel and hard clay layers or weathered, very cracked weak rocks ZB; It can be defined as slightly weathered, moderately strong rocks. Removability values according to Vp wave velocity were evaluated as Medium for the first layer, and Difficult/Extremely Difficult for the second layer. The Vp/Vs ratio of the area changes as Layer 1 Loose/Solid/Tight-Solid/Strong, Layer 2 Loose/Very Loose. The boundaries and units of the geological formations of the ground in the region have been determined. Limestone and fill surface slip surfaces in the area were observed in MASW sections. By evaluating all these studies together, the mass movement in the region was determined as slow flow (creep).
