The urban tram project, which operates with a light rail system, is planned. In addition to metaformic, sedimentary and magmatic rocks on the ground, unconsolidated fine sand-silt grain size ground materials were also found. Underground water level depth is between 1 and 3 meters. There is a fault zone along the project line. What can be the geotechnical problems that may be encountered before, during and after the project construction, and solutions as a civil engineer?
