Dr Alfred Stärk is Chief Geotechnical Engineer and Engineering Manager at BBMV for Crossrail Contract 510 ‘Whitechapel and Liverpool Street Station Tunnels’ since March of 2011. He started his career at the University of Hanover, Germany, where he worked as assistant professor and consultant for 10 years. In 2002 he joined BeMo Tunnelling, Innsbruck, Austria. He now has 25 years of experience in large-scale tunnelling, mainly with sprayed concrete lining in soft ground.
The Crossrail station at Liverpool Street, London required the downward construction of a 37m long by 6m diameter inclined ventilation tunnel using...
In 2011 BBMV C510 Joint Venture was awarded the contract for the construction of the Vallance Garden Crossover tunnel. Originally the Crossover was...
From its unveiling in 1927, the Post Office tunnel provided much of London’s mail and parcel transportation across the city, all the way up to it...
To understand the behaviour of the tunnel lining and the ground during the construction of tunnels and shafts is not only important to determine ve...
Accurate ground water monitoring is vital during tunnel excavation in soft soils, not only for the stability of the excavation itself, but also for...
Predictions of ground movements due to tunnelling extensively rely on empirical methods based on published case studies of tunnels constructed in s...
The displacements of sprayed concrete lining must be measured during tunnel excavation. In order to assess stability the displacements are checked ...
Long-term settlement at the start of the project was considered marginal and was believed to not be significant in comparison to the magnitude of t...
This paper provides a comparison of predicted and measured displacements and deformations for SCL tunnels at Crossrail C510 Whitechapel Station. It...
The platform and pedestrian tunnels for the Crossrail Stations at Whitechapel and Liverpool Street have been constructed using Sprayed Concrete Lin...
