Future trends in the structural design of tunnels
AbstractA design in engineering is based on conceptual models of outer actions (loads), stress-strain behaviour, failure criteria; it tries to predict these phenomena within the projected lifetime of the structure. For underground structures, the design must take into account the actions and reactions of the ground caused by tunnelling; the strength properties of ground and structural supports; and possible failure modes during and after excavation. What are the trends foreseeable at present towards future developments of those items entering into the structural design of tunnels? This paper tries to project developments, e.g. in the fields of extracting ground parameters, computer-aided excavation and computer-aided evaluation of monitoring, defining numerical analysis, etc. A summary lists the most promising fields of work for further developments in the structural design of tunnels and caverns.
RésuméLa partie technique d'une conception est base´e sur des mode`les conceptuels des actions exte´rieures (les forces), du comportement effort-de´formation, des crite`res de rupture. On essaie de pre´dire ces phénome`nes pour la dure´e de vie anticipe´e de la structure. Pour des structures sous-terraines, on doit prendre en conside´ration les actions et les re´actions du sol cause´es par le tunnel, la re´sistance du sol et celle des supports structurels, ainsi que les modes de rupture pendant et apre`s l'excavation. Quels sont les tendances que l'on peut pre´voir quant au de´veloppement de ces conside´rations qui entrent dans la conception structurelle d'un tunnel? Cet article tente de pre´voir ces de´veloppements, par example dans le domaine des prises de donne´es du sol, dans l'excavation et le controˆle assiste´par ordinateur, dans le raffinement des analyses nume´riques, etc ... Un re´sume´liste les domaines les plus prometteurs quant au de´veloppement de la conception structurelle des tunnels et des cavernes.
