Abstract

Maintenance need to be provided as the tunnel has serves such a long time and it is to ensure no severe failure in the tunnel will occur that would lead to the unwanted causalities. This paper presents visual condition assessment of tunnels of hydroelectric power station to determine deterioration level of shotcrete lining based on FHWA, and CIRIA report C671. From the assessment, it is found that 40% of leakage condition is in rating 2 for MAT and 63% also leakage in rating 2 for CVT. The most severe area is along Chainage 0+300 for MAT and Chainage 0+400 for CVT. Shotcrete lining is also found able to function properly to provide drainage diverting the leaking.
