Underground construction instability has been a major cause of undesirable accidents, especially in those which are related to transportation. Experience feedback is one of the useful methods available to improve the design of construction. The main first part of this paper is to present a database, which has been developed to record instabilities of affected tunnels and other underground constructions around the world, at both phases of construction or exploitation. The second part aims to analyse all the parameters responsible for instability phenomena and to assess their impact on the affected construction itself as well as on neighbouring constructions and the environment where they reflect effects on human safety and activities. Our future aim is to develop a risk analysis methodology to help engineers for taking safety issues better into account in the design of underground infrastructures.
