Field instrumentation was installed to monitor ground and lining behaviour during and after construction of tunnels of a project in Taiwan. The instrumentation was placed in a soft ground, soft rock and hard rock. The project was excavated through a " Pre-Tertiary Metamorphic complex". The field data are presented and interpreted in geological-geotechnical point of view. The ground movement due to the tunnel excavation was found to be large. This has been attributed to the low to medium strength and stiffness of the rock mass as well as the weak planes in the rock mass. Evaluation using the Boundary Element method was conducted so that the results can be compared with the measurement data and suitable interpretation of ground response can be obtained. Q- system slightly predicts the actual support requirements for the worse grounds of this tunnel .
