This article reports on a talk given to the British Tunnelling Society describing aspects of constructing the Channel Tunnel from the French side. The complexity of the geology and a high water content led to differences in tunnelling machines and slurry disposal. Characteristics of the earth pressure balance machines used are listed. Problems encountered with the tunnelling machines and how they were overcome are outlined. A comparison is made between machines used on the French and UK sides in terms of machine type, lining design, access to tunnels, muck removal, machine availability and productivity. Tunnel lining segments on the French side are made from a dense impermeable concrete without PFA. Details are given of the discussion which followed.
