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.
The Tunnel Engineering Handbook, Second Edition provides, in a single convenient volume, comprehensive coverage of the state of the art in the design, construction, and rehabilitation of tunnels. It brings together essential information on all the principal classifications of tunnels, including soft ground, hard rock, immersed tube and cut-and Cited by: Cut and Cover tunnels, which are excavated in a trench and roofed over with a concrete support,3 are artificial tunnels, and significantly differ from excavated tunnels. Nevertheless, they are included in the analysis, as they represent a common practice in rail infrastructure deployment when mild ground level variations are Size: KB.

Cut-and-cover is the oldest method of tunneling. The basic concept involves the digging of a trench, the construction of a tunnel, and then returning the surface to its original state.
As such, it is a disruptive technique, but it is also usually the most economical construction method. 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.

of Transportation, Federal Highway Administration, Office of Research and Development ; Springfield, Va.: For sale by the National Technical Information Service, For depths of 30 to 40 feet (about 10 m to 12 m), cut-and-cover is usually more economical and more practical than mined or bored tunneling.
The cut-and-cover tunnel is usually designed as a rigid frame box structure. In urban areas, due to the limited available space, the tunnel is usually constructed within a neat excavation line using braced.
Cut and cover tunnel design with DeepEX. 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.

THE “CUT AND COVER” CONSTRUCTION PROCESS The “cut and cover” technique is a simple construction method widely applied in both urban and rural tunneling projects. The main prerequisites for application of the method are the dominance of soft or weak ground conditions and/or low overburden.

Tunnel Boring vs Cut and Cover. Posted by Anonymous on Monday, J AM By Tunnel boring, I will assume that you mean shield tunneling, as was used on the first St. Clair tunnel. To avoid disrupting utilities, including sewers, you would have to go very deep, anything over 40 feet below ground level would not be practicable.
Curbed LA writes about a partial court victory for downtown LA businesses that object to the “cut-and-cover” tunneling method in LA’s new regional connector light rail line. The line will travel through downtown LA, providing a badly needed link between the light rail lines ending at Union Station and beginning at the Blue/Expo Line stations not far from Staples.
Cut-and-Cover Structures Surface tunnelling encompasses all construction methods of underground structures built by a temporary or permanent open trench in the surface. The construction sequence of surface tunneling is composed of the following steps.

Upon completion of the structure, backfilling and reinstatement would be subsequently carried out.Bottom-up tunneling; Cut and cover tunneling; Shallow-depth tunneling Definition Cut and cover is a tunnel construction technique, preferred at a shallow depth, in which excavation can be economically performed from the surface and the trench is subsequently covered with backfill after installation of all components for tunnel structures.A tunnel construction is an underground passage provided beneath earth surface or water.
Different methods of tunnel construction and their details are discussed. In most of the cases tunnel construction is expensive but it saves time and provides comfort. Large excavation of soil or rock etc. is necessary for a tunnel : Sadanandam Anupoju.
