TUNNELLING UNDER SQUEEZING CONDITIONS: A CASE HISTORY - MANERI BHOLI STAGE II PROJECT, INDIA . TUNNEL CONSTRUCTION 90. PAPERS PRESENTED AT THE TUNNEL CONSTRUCTION 90 CONFERENCE, ORGANIZED BY THE INSTITUTION OF MINING AND METALLURGY, LONDON, 3-4 APRIL, 1990

A large number of tunnels, driven in young and fragile rocks of Himalaya have experienced several tunnelling problems. A 16 km long horseshoe shaped tunnel, of 6 m diameter, of Maneri Bhali Stage-II Project has suffered a major tunnelling problem of severe squeezing ground condition. A failure study, on the tunnel under squeezing is presented in the paper. The results obtained from instrumentation and empirical approach for squeezing and non-squeezing strata are discussed. Himalayan tunnels are long and are always a critical component of projects. Thus, the feasibility of deploying a Tunnelling Boring Machine is also briefly discussed.(A) For the covering abstract of the conference see IRRD 828810.
