Abstract

Abstract: Many geological hazards might be encountered in tunnel excavations and some might adversely affect construction safety. This case history presents the prediction of geological conditions by using ground penetrating radar. Throughout construction, it is concluded that this method could reasonably detect the joints and groundwater in the rock mass in front of the excavation. This information provides bases for the excavation and support. Combining the prediction and the construction monitoring results can provide an effective way to justify the stability of the rock mass and ensure a safe tunnel construction.

Key words: Tunnels, Geological Condition Prediction, Construction Monitoring
