Geotechnical assessment and engineering classification of the Antalya tufa rock, southern Turkey

Sopacı, Evrim

This study mineralogically and geotechnically assesses the Antalya tufa rock types, which are highly variable in nature. Geological observations, geotechnical site investigations, and in-situ and laboratory tests have been performed to determine the parameters (i.e., organic matter content, rock fabric, apparent porosity, unit weight, uniaxial compressive strength, Young's modulus, tensile strength, cohesion and angle of internal friction) that may have a significant influence on tufa rock behavior and to develop a comprehensive geotechnical database for the Antalya tufa rock. The geotechnical database was utilized for the engineering classification of the Antalya tufa rocks using the GSI classification system.
