Application of geophysical investigations in underground engineering

Geophysical methods are non-destructive methods that have numerous advantages in relation to conventional geotechnical survey, primarily from the aspect of saving time and economic resources. They are used in underground engineering for determining geological- structural and physical- mechanical characteristics of subsoil. Determining the physical-mechanical characteristics most often involves determining the stiffness of subsoil and rock mass at small strains. An overview of geophysical methods significant in engineering practice is given including examples of successful implementation of geophysical methods in Croatia. Geophysical methods are used in combination with boreholes works, as preliminary phase of surveys for a more complete image of underground and better possibilities of interpretation of geological structures.
