Back-Calculation of the Shear Strength Parameters of Subgrade Soil Based on Lightweight Deflectometer Test Using 3D Numerical Modeling
Kadakçı Koca, Tümay (SPRINGER, 2022)The undisturbed sampling from natural carbonate gravel-bearing subgrade soil for shear strength tests is a challenging process, or in-situ tests are costly and require time. In addition, mechanical properties of soils, ... -
A combined application of two soft computing algorithms for weathering degree quantification of andesitic rocks
Kadakçı Koca, Tümay; Köken, Ekin (Elsevier B.V., 2022)Understanding the variations in physical and mechanical behavior of rock materials due to progressive weathering is vital to carry on time and cost-effective engineering projects. Up to date, soft computing algorithms have ... -
A comparative study to estimate the mode I fracture toughness of rocks using several soft computing techniques
Köken, Ekin; Kadakçı Koca, Tümay (Turkish Journal of Engineering, 2023)Fracture toughness is an important phenomenon to reveal the actual strength of fractured rock materials. It is, therefore, crucial to use the fracture toughness models principally for simulating the performance of fractured ... -
A Conceptual Sector-Scale Numerical Modeling of a Landslide in an Open Pit Mine
Kadakçı Koca, Tümay (Polska Akademia Nauk, 2022)In this study, an old rotational landslide that has reactivated in the NW sector of an open-pit mine operated within the gneiss rock unit was evaluated for geological and hydrogeological properties. The pit slopes were ... -
Determining the inclination angles of anchor bolts for sliding and toppling failures: a case study of İzmir, Türkiye
Koca, Mehmet Yalçın; Kıncal, Cem; Onur, Ahmet Hakan; Kadakçı Koca, Tümay (Springer Science and Business Media Deutschland GmbH, 2023)When anchors are installed along or close to discontinuity surfaces in a jointed rock slope, it is very difficult for them to bond to the rock mass. The correct orientation of rock anchors should be selected for precise ... -
The Effect of Geometrical Features of Release Surfaces on the Stability of Tectonically Disturbed Deep Rock Slopes in an Albite Open Pit Mine
Kadakçı Koca, Tümay (MDPI, 2023)An albite deposit formed in orthogneiss has been operated using open pit mining process since 1996. However, landslides have occurred following the excavation works and heavy rainfalls. In the current state, the slopes are ... -
Farklı ayrışma derecesindeki andezitlerde mikrokırık sıklığı ve mikrokırık uzunluğundaki değişimin incelenmesi: İzmir-Bayraklı andezit taş ocakları örneği
Koca, Mehmet Yalçın; Kadakcı Koca, Tümay (Hacettepe Universitesi Yerbilmleri, 2023)zmir, Bayraklı ilçesi, Çiçek mahallesinde bulunan terkedilmiş andezit taş ocakları günümüzde yerleşim alanı içerisinde kalmaktadır. Farklı ayrışma derecelerindeki andezitlerde artan boşluk suyu basıncı ve ayrışma derecesine ... -
Finite element and empirical solutions for estimating bearing capacity and settlement of a jointed, multi-layered dam rock foundation
Kadakçı Koca, Tümay; Koca, Mehmet Yalçın (Springer, 2022)Abstract: This study discusses the bearing capacity and settlement behaviour of highly jointed mica-schist rock mass that is divided into multilayers along depth beneath the foundation of Burgaz Dam in İzmir, Turkey. These ... -
Studying the Effects of Forest Fire on the Consistency Limits of Sandy Soils: A Case Study, Kozağaç, Muğla
Kadakçı Koca, Tümay (TMMOB Chamber of Geological Engineers, 2022)The changes in physical, chemical, and mineralogical properties of topsoil after forest fires, and their effect on erosion risk, have been previously studied in different geographical regions and ecosystems. It is well ...
