Numerous tunnels in the United States are more than 50 years old and are beginning to show signs of considerable deterioration, especially due to water infiltration. This course provides information and procedures for the inspection of both highway and rail transit tunnels.
The main focus of the course is on the civil/structural, mechanical, and electrical components, as well as ventilation and lighting. However, brief guidance is also provided for other systems/appurtenances specific to rail transit tunnels, including tracks, traction power, signals, and communications. This brief guidance is only meant to provide general knowledge and not in-depth inspection criteria for such systems/appurtenances.
The course also covers various tunnel shapes and liner types, the two main invert types, the various construction methods used to construct a tunnel, and the different finishes that typically exist in highway tunnels.
