Risk Analysis of Tunnels
Author: Prívara Samuel
Many approaches to Risk Analysis in tunnels have been proposed by both international and national authorities over the last few years. They address the specific environment of tunnels and try to estimate the risk levels in order to diminish it in an affective manner to make the tunnels safer. Many topics have been discussed and a large number of important risk factors and hazards in tunnels have been identified. However, the concept of Risk Analysis in the scope of tunnel risks is still under development; particularly an overall idea about the Risk Management concept is still missing.
This thesis introduces the concept of Risk Analysis in the scope of Risk Management trying to both explain traditional methods used in Risk Analysis and employs methods well-known in aeronautics and aircraft industry, yet, still unused and unknown in tunnels. The objective of this thesis also includes a case study of Strahov Tunel which uses Risk Analysis methods traditionally used by aircraft industry – particularly National Aeronautics and Space Administration (NASA), Federal Aviation Association (FAA) and United States Department of Defence (DoD). The Risk Analysis proposed in Chapter 3 – Case Study was developed for Strahov Tunnel (as a part of Technical Documentation), where it was applied as of 2009. This method is supposed to be applied for other Czech tunnels, especially new tunnels built in Prague, e.g. Blanka tunnel.
