TUNNELING IN BELGIUM

摘要

Wayss & Freytag Ingenieurbau AG is currently constructing three major infrastructure projects in Belgium. The paper will highlight some of the construction challenges of the projects and the sometimes quite unique construction methods developed and successfully implemented on those projects. Some of the challenges were: tunneling under the live runways of Brussels International Airport; construction of a railway tunnel underneath an existing road tunnel in the heart of Brussels utilizing hand-dug diaphragm walls and pipe-jacking and finally slurry TBM tunneling under the harbor of Antwerp with minimal cover.
