Underground – how to the future was once the motto of the realm Tunnel Congress 2013 in Geneva, Switzerland. using underground area has received value over the last years as a result of the large worldwide urbanization, the excessive call for on transportation capacities and effort creation. All this lead to a much wider diversity of use of underground house: in addition to the normal highway, railway, metro and software tunnels, a growing number of different functionalities of contemporary lifestyles are put below flooring with a view to loose the outside for different makes use of. The three hundred papers of the current e-book hide very important points of contemporary underground infrastructures: improvement and use of underground house; undertaking making plans and implementation (construction administration, hazard keep an eye on, price estimation and scheduling, contracting practices); layout and research equipment and issues; development know-how advancements; tunnel operation (safety, upkeep, rehabilitation and repair); case histories (learning from mess ups, lengthy deep tunnels, underground development for hydropower).

Underground – easy methods to the future could be worthwhile to experts, contractors and layout engineers in underground making plans, development and tunnelling world wide, and to teachers drawn to underground and geotechnical engineering.

Wells wrote in 1985 “The Time Machine” and how he foresaw the cities of the future. He predicted that people would increasingly live in urban centres and that industry and “less ornamental purposes of civilization “ would be located underground with above ground being green and leafy. So far things have not turned out quite as he predicted with heavy industry no longer centered in our major cities. However, there is an increasing demand to develop our urban centres rather more green and leafy and make urban living more user friendly.

Launch Boxes are constructed to provide an underground structure from which TBM’s can be built and launched to construct the running tunnels. They then provide the basic structure within which the permanent station is constructed. Typically launch boxes will be 22-24 m span and around 200 m long. The height will be determined by the diameter of tunnel to be driven but for a twin track tunnel this could be 6-7 m diameter with internal depth of box up to 8-10 m. These would be driven from a central access shaft in both directions using the jacked deck method to give the clear spans required.

The decision to construct the facility underground rather than on a greenfield site was finally based on the economic advantage resulting from decreased installation costs associated with the vibration sensitive equipment required for silicon wafer chip production. Open greenfield solutions, especially when constructed on soft ground, require a sophisticated foundation concept to damp vibrations which arise either from chip production or from far-field noise and vibrations. The owner of the production facility, Espros Photonics Corporation Ltd.
