The definition of what constitutes a tunnel can vary widely from source to source. For example, the definition of a road tunnel in the [[United Kingdom]] is defined as "a subsurface highway structure enclosed for a length of {{convert|150|m|ft}} or more."<ref>{{cite book|title=DESIGN MANUAL FOR ROADS AND BRIDGES: VOLUME 2: SECTION 2: PART 9: BD 78/99: DESIGN OF ROAD TUNNELS|year=1999|publisher=The Department for Transport|url=http://www.dft.gov.uk/ha/standards/dmrb/vol2/section2/bd7899.pdf}}</ref> In the United States, the [[National Fire Protection Association|NFPA]] definition of a tunnel is "An underground structure with a design length greater than {{convert|23|m|ft|abbr=on}} and a diameter greater than {{convert|1800|mm|ft}}."<ref>{{cite book|title=NFPA Standard for Safeguarding Construction, Alteration, and Demolition Operations|publisher=National Fire Protection Association}}</ref>

== Геотехничко истраживање и пројектовање ==
{{Main|Геотехничка истраживања}}

A major tunnel project must start with a comprehensive investigation of ground conditions by collecting samples from [[borehole]]s and by other geophysical techniques. An informed choice can then be made of machinery and methods for excavation and ground support, which will reduce the risk of encountering unforeseen ground conditions. In planning the route, the horizontal and vertical alignments can be selected to make use of the best ground and water conditions. It is common practice to locate a tunnel deeper than otherwise would be required, in order to excavate through solid rock or other material that is easier to support during construction.

Conventional desk and preliminary site studies may yield insufficient information to assess such factors as the blocky nature of rocks, the exact location of fault zones, or the stand-up times of softer ground. This may be a particular concern in large-diameter tunnels. To give more information, a pilot tunnel (or "drift tunnel") may be driven ahead of the main excavation. This smaller tunnel is less likely to collapse catastrophically should unexpected conditions be met, and it can be incorporated into the final tunnel or used as a backup or emergency escape passage. Alternatively, horizontal boreholes may sometimes be drilled ahead of the advancing tunnel face.

Other key geotechnical factors:
* '''Stand-up time''' is the amount of time a newly excavated cavity can support itself without any added structures. Knowing this parameter allows the engineers to determine how far an excavation can proceed before support is needed, which in turn affects the speed, efficiency, and cost of construction. Generally, certain configurations of rock and clay will have the greatest stand-up time, while sand and fine soils will have a much lower stand-up time.<ref>{{cite book |editor1-last= Bickel|editor1-first= John O.|editor2-first =Thomas R.|editor2-last = Kuesel |editor3-first=Elwyn H.|editor3-last =King|page = 210|date = 2004|title= Tunnel Engineering Handbook|edition = 2nd|publisher =Kluwer Academic Publishers|chapter = Tunnel Boring Machines|first = Harry|last = Sutcliffe|chapter-url = https://books.google.com/books?id=59V5BgAAQBAJ&pg=PA210|isbn = 978-1-4613-8053-5}}</ref>
* [[Groundwater]] control is very important in tunnel construction. Water leaking into a tunnel or vertical shaft will greatly decrease stand-up time, causing the excavation to become unstable and risking collapse. The most common way to control groundwater is to install dewatering pipes into the ground and to simply pump the water out.<ref>Powers, P.J. (2007). Construction dewatering and groundwater control. Hoboken, NJ: John Wiley & Sons Inc.</ref> A very effective but expensive technology is [[ground freezing]], using pipes which are inserted into the ground surrounding the excavation, which are then cooled with special refrigerant fluids. This freezes the ground around each pipe until the whole space is surrounded with frozen soil, keeping water out until a permanent structure can be built.
* Tunnel [[Cross section (geometry)|cross-sectional shape]] is also very important in determining stand-up time. If a tunnel excavation is wider than it is high, it will have a harder time supporting itself, decreasing its stand-up time. A square or rectangular excavation is more difficult to make self-supporting, because of a concentration of [[Stress (mechanics)|stress]] at the corners.<ref name="Engineers. 1978"/>

Терминологија

An entrance of the Rantaväylä Tunnel in the northern part of Tampere, Pirkanmaa, Finland

A tunnel is relatively long and narrow; the length is often much greater than twice the diameter, although similar shorter excavations can be constructed, such as cross passages between tunnels.

The definition of what constitutes a tunnel can vary widely from source to source. For example, the definition of a road tunnel in the United Kingdom is defined as "a subsurface highway structure enclosed for a length of 150 m (490 ft) or more."[1] In the United States, the NFPA definition of a tunnel is "An underground structure with a design length greater than 23 m (75 ft) and a diameter greater than 1.800 mm (5,9 ft)."[2]

Геотехничко истраживање и пројектовање

A major tunnel project must start with a comprehensive investigation of ground conditions by collecting samples from boreholes and by other geophysical techniques. An informed choice can then be made of machinery and methods for excavation and ground support, which will reduce the risk of encountering unforeseen ground conditions. In planning the route, the horizontal and vertical alignments can be selected to make use of the best ground and water conditions. It is common practice to locate a tunnel deeper than otherwise would be required, in order to excavate through solid rock or other material that is easier to support during construction.

Conventional desk and preliminary site studies may yield insufficient information to assess such factors as the blocky nature of rocks, the exact location of fault zones, or the stand-up times of softer ground. This may be a particular concern in large-diameter tunnels. To give more information, a pilot tunnel (or "drift tunnel") may be driven ahead of the main excavation. This smaller tunnel is less likely to collapse catastrophically should unexpected conditions be met, and it can be incorporated into the final tunnel or used as a backup or emergency escape passage. Alternatively, horizontal boreholes may sometimes be drilled ahead of the advancing tunnel face.

Градња тунела

Изградња Метро-тунела Париског метроа

Градња тунела се врши из неколико корака:

  • геотехничко испитивање - обично се састоји од низа студија о квалитету земљишта (анализе стена, дебљина слојева), на основу којих се одређују особине будућег тунела, као и начин градње. У неким случајевима, потребно је изградити и тзв. „пилот-тунеле“, као претходницу главних.
  • Изградња тунела може се вршити путем неколико начина:
