Decision making tool for the choice of maintenance strategies of tunnels

Résumé

The current inspection strategy applied to tunnels is mainly based on visual inspection. However, this type of inspection only detects apparent damages without linking them to their causes. A new monitoring methodology has been proposed consisting in integrating monitoring tools to better characterize the geometrical and mechanical state of different tunnel components (lining, contact interface and surrounding ground). This methodology has been developed in the context of the ANR MEDITOSS project. In this context a maintenance tool is developed. This paper is dedicated, on the one hand to the presentation of the provided tool and on the other hand to the results of ten cases study, based on three RATP stations, that can provide the influence analysis of: (1) monitoring notes according to MEDITOSS methodology, (2) performance level targeted, (3) assignment date of budgets and (4) intervention priority according to the damage character.
