Abstract (en)
The tunnel multi deck is a roadway tunnel of circular cross section (1), with two-way separated, characterized by having two slabs (2) (3) along its full width, one placed roughly at the half height of the tunnel and the other placed slightly above the bottom of the tunnel, in order to create three overlapping galleries, isolated and independent: two identical roadway galleries (4) (5), one for each way of traffic, and a service gallery (6), at the bottom. The slabs (2) (3) have openings (7), placed close to the circular wall of the tunnel (1), in one or in both sides, regularly spaced and protected with fireguard devices of box type (8), which are connected through closed vertical access galleries (10), to allow for safe passage of people from the roadway galleries (4) (5) to the service gallery (6). The service gallery (6) is provided with emergency vehicles of shuttle-type (9), circulating suspended from the slab (3), to allow for the access of personnel and the evacuation of people in case of accident or fire inside the tunnel.
