    Geoengineering Properties of the Ertugrul (cayirkoy) District, Nilufer Province, Bursa-Turkey, by Using Geophysical Methods and Borehole Data
    (Elsevier, 2020) Cetin, Fatma; Kutluk, Hatice; Aydemir, Attila
    In this study, soil classification experiments and geophysical studies are carried out for the evaluation of local ground soil conditions by using the data and samples from the boreholes in the Quaternary sediments in the Ertugrul district of Nilufer, Bursa, then the engineering parameters and index classifications are also investigated with the soil mechanics experiments using the disturbed samples from the drill holes. The grade of swelling (bulking) potential in the ground soil is found medium, high and very high in different parts of the study area. The basement units for the constructions bear very low liquefaction risk. The plasticity index varies between 9 and 25, but active mass movements are not expected. However, engineering problems such as swelling (bulking), soil settlements, bearing capacity reduction may be expected under the seismic forces because of the alluvial composition, 0-5 degree soil inclinations and being located in the 1st degree earthquake hazard risk zone. Therefore, the study area may be classified in the 'precautionary zone' in the urbanization category in terms of engineering problems. (C) 2020 Elsevier B.V. All rights reserved.
