    Shallow-depth tunnels, such as large sewer tunnels, vehicular tunnels, and rapid transit tunnels, are frequently designed as structures to be constructed using the cut-and-cover method. Tunnel construction is characterized as “cut-and-cover” construction when the tunnel structure is constructed in a braced, trench-type excavation (“cut Cited by: 2.

    A frame-shaped cut-and-cover tunnel is first considered, and more specifically the construction phase when the backfill reaches the top of the side walls. The situation, the failure mechanism and the characteristic values are represented in Figure 1a. Figure 2a shows the characteristic curve of the soil (1) calculated according to the approach.   Tunnel Construction Methods and their comparison. 1. Introduction – This paper gives a general description of the tunnelling techniques such as cut and cover, drill and blast, bored tunnelling and sequential mining construction, reviewed for possible use in various projects. A summary of environmental merits and demerits associated with these methods are also given.
