Recent dutch experiences in developing structural monitoring systems for shield driven tunnels
article
This paper discusses two major structural monitoring programs that have been recently conducted in the Netherlands in the Second Heinenoord tunnel and Botlek Railway tunnel respectively. The Second Heinenoord tunnel was the first large diameter shield driven tunnel in The Netherlands. It was constructed in the period March 1997 to July 1998. Because of to its novel construction technique for the Dutch building community, a large monitoring program accompanied the construction of the lining. This paper focusses on the structural monitoring program at the Second Heinenoord tunnel. The monitoring concept, the execution of the monitoring and the lessons learned are discussed. Subsequently, the enhanced monitoring program for the Botlek Railway tunnel, that was conducted in 2000, is presented. Finally, some future developments in monitoring the structural behaviour of shield driven tunnels are discussed.
