Abstract:
Cracking in tunnel lining is a major cause for reduction in serviceability due to water infiltration and exfiltration, and reinforcement corrosion. In order to control water inflow in lined tunnels, design codes and guidelines limit maximum crack width. However, correlation between the allowable crack width and corresponding water inflow in tunnel has not been provided. This paper discusses effects of fiber reinforcement in reduction of
flexural crack width, and provides a relationship between crack width and water inflow to verify merits of current crack width criteria for design and construction of concrete tunnel linings.
