Liquefaction Potential Analysis and Mapping of Alluvium Soil: A Case Study in Nazilli-Aydın (West Turkey)

Öz

The importance of urban planning for sustainable cities is indispensable. For this, the preparation of geotechnical maps, especially, comes to the agenda. Liquefaction susceptibility mapping is important for towns located in first-degree earthquake regions. This study investigated the susceptibility to liquefaction in a possible earthquake in Nazilli (Aydın) county in light of geologic and geotechnical studies. In line with this, firstly drilling was completed at 110 points, with experiments performed on location and geotechnical properties determined in soil samples taken during this process. Generally, the county is founded on alluvial soils with groundwater very close to the surface. This situation makes it important to determine the liquefaction status of the town during a possible earthquake. The liquefaction potential (FL) of the study area was determined with the simplified SPT based method and additionally the liquefaction potential index (LI) was calculated. Using this data and an ArcGIS program, the FL and LI maps of the study area were prepared. According to the results obtained, the majority of the study area has very high liquefaction potential index.
