181-187p. The lates underground works show how the tunnel boring machines can face more and more difficult conditions. An example of this trend is the Groene Hart tunnel, part of the High Speed Link dutch network, at present under construction by the Bouygues-Koop Consurtium. This tunnel, with about 15m diameter, was bored with the world largest confining tunnel boring machine (TBM) up to now. On the tunnel track, measuring more than 7km, many requirements have to be fulfilled. In partiticular, in a soil extremely sensitice to the buildings, roads, railways and utilities. Besides, the specific geotechnical condistions created by polders induce a very notable and quite uncommon phenomenon of increase of the natural pore pressure in soil (called Excess pore Preassure or EPP) during boring which can effect tunnel cover stability, Therefore, detailed monitoring campaigns aimed at better understanding the hydraulic and mechanical soil behaviour have been carried out at different locations on the track.
