Abstract
A comprehensive subsurface investigation program was conducted to delineate the soil, rock and groundwater conditions in subject area of the project site located in Gulf Region consisted mainly of land-based geotechnical drilling. In the scope of this study, the onshore site characterization is based on an integrated approach that combines the site specific data collected from borings, field and laboratory tests. Within the scope of laboratory studies, relationships between strength properties of rock samples and drilling rate index were examined. For this purpose, uniaxial compression test, Schmidt hammer rebound test and drillability test were conducted for the rock samples which were collected from different rotary drilling boreholes. The experimental studies have shown that the drilling rate index (DRI) decreases with the increasing uniaxial compressive strength (UCS) and Schmidt Hammer Rebound Hardness (SHRH).
