STARTING AND END SHAFTS OF THE SOPHIA RAILWAY TUNNEL

The Sophia railway tunnel in the west of the Netherlands is at the moment under construction as part of the Betuwelijn railway line, a freight line from the port of Rotterdam to Zevenaar near the German border. In this paper the design of the shafts at which the bored tunnel starts and ends will be discussed from a geotechnical point of view. Much attention will be paid to the equilibrium and the deformations of the shafts. The vertical equilibrium is an important item in the Netherlands, due to the very high ground water table. Because the starting shaft is unique in the absence of tension piles or anchors, the Dutch Center for Underground Construction (CUR-COB) used the opportunity to install test equipment to observe the heave at three depths under the shaft and to observe the behavior of the earth and water pressures. These data will be used for future deep building pits in the Netherlands, such as the North South metro line stations in Amsterdam.
