ABSTRACT

The paper presents a review of testing methods and a classification of strategies and tools in terms of technologies and techniques applied to the monitoring of tunnels during rehabilitation measures. There is a need of an assessment tool to correctly use classic and innovative monitoring systems while surveying existing tunnel system before and after tunneling rehabilitation measures. A uniform classification of monitoring methods and their suitability is presented in this contribution with respect to standards and the successive implementation steps. The whole analysis is based on European international research projects as well as on the record of many years of practical experience and implementation of monitoring management systems. The form of the monitoring system evaluation below is on masonry tunnels that are in need of rehabilitation.
