Tunnel - Wikipedia
Cut and cover construction is used when the tunnel profile is shallow and the excavation from the surface is possible, economical, and acceptable. Cut and cover construction is used for underpasses, the approach sections to mined tunnels and for tunnels in flat terrain or where it is advantageous to construct the tunnel at a shallow depth.
Cut and Cover
Cut and cover method of tunnel construction is generally used to build shallow tunnels. In this method, a trench is cut in the soil and it is covered by some support which can be capable of bearing load on it.
Methods of Tunnel Construction and Their Details
The construction method (Drill and Blast method, Cut and Cover method, Tunnel Boring or Immersed Tube Tunnel) to be adopted will depend on various factors, such as topography and geology, etc. Move your cursor over different colour sections to view more details of the construction methods.

Cut and cover construction is one of the methods that will be used to build the new Metro Tunnel stations. As the name suggests, cut and cover construction involves using excavation equipment to dig a large trench or rectangular hole in the ground which is then covered by a concrete deck.
Tunnel construction - Wikipedia
Cut and cover tunnel design involves the consideration of many parameters. Cut-and-cover is a simple method of construction for shallow tunnels where a section is first is excavated and then covered over with an overhead support system strong enough to carry the load of what is to be built above the tunnel.

2. Construction Methods 2.1 Cut and Cover Tunnelling Cut and cover tunnelling is a common and well-proven technique for constructing shallow tunnels. The method can accommodate changes in tunnel width and non-uniform shapes and is often adopted in construction of stations.
Cut and cover - Metro Tunnel
Cut and cover is the oldest method of tunnelling: the basic concept involves the digging of a trench, the construction of a tunnel, and then returning the surface to its original state.
