Özet:

Among the major engineering structures built in recent years, dams are one of the important

engineering structures that need to be meticulously handled with pre-feasibility studies and

seriously evaluated in terms of their technical and economic feasibility to come up with the most

appropriate engineering solutions. Therefore, determination of permeability of rock masses in axis

location and lake area is the most important parameter before construction. In this study, it is aimed

to determine the permeability of the rock mass in the Bayburt-Kırklartepe dam site by getting help

from the data obtained from the geophysical methods that can collect data covering the entire area

of the rock mass with lower costs and less permeability of the rock mass as well as considering the

field characteristics and project features and minimizing the use of drilling operations and

pressurized water tests (BST) which are difficult and costly to implement. In this context, the

empirical equations for determining the permeability of the rock mass have been proposed by

comparing the Lugeon values obtained from on-site BST tests and geophysical and geotechnical

parameters. Among these equations, Schmidt hardness, P and S wave velocity (Vp, Vs) and

resistivity values, and Lugeon values were taken into consideration as parameters affecting the

permeability of rock mass, and the permeability classification of metamorphic rock mass was

formed. As a result of the statistical evaluations and zoning for dam axis location, it was

determined that the metamorphic rock mass spreading in the study area has a permeability

characteristic by comparing lithological depth, Schmidt hardness, Vp, Vs and resistivity values in

the permeability classification which was formed by considering the Lugeon permeability class

intervals. The best performing equations in the statistical analyses were found between LU-Vp and

LU-Vs. Finally, Pulur metamorphic rock mass was limited to nonpermeable and high-permeable

value ranges according to Lugeon class ranges. Vp, Vs and resistivity values were found between;

2000-3500 m/s, 950-1300 m/s and 300-950 Ohm.m for nonpermeable rock mass, and 950-2000

m/s, 550-950 m/s and 10-300 Ohm.m for high-permeable rock mass, respectively.
