 ABSTRACT

This paper mainly focuses on pre-investigations and on optimal extent of preliminary investigations. Different investigation methods are tested in varying geological conditions. In this paper results from site investigation carried out on Ghomroud Tunnel are discussed and compared with what have been encountered in geological conditions and water leakage during excavation. The rock types are, however, quite different.

Keywords: Engineering geology, tunnel, water inflow, rock properties
