TUNNEL SUPPORTS

SOSTENIMIENTO DE TUNELES

The driving of a tunnel makes the surrounding soil unstable and creates conditions favourable to a cave-in. The movements which are produced may be slow or very violent, and these place in danger not only the tunnel structure but also structures on the surface. This problem is generally resolved by placing in position a temporary lining, either independent of or integral with the interior face of the tunnel. The article studies the temporary lining, analysing the different methods and materials employed: timber, metal, with anchor bolts, with shotcreting and using mixed processes. (TRRL)
