ABSTRACT
The two bored tunnels that will be part of the North/South metroline under the city centre of Amsterdam are characterized by an innovative design of radial and circular joints. This innovative joint design calls for an innovative and advanced numerical model of the joints and the tunnel tube as a whole. While developing the 3-D phased model of the tunnel lining and its components the vast array of modeling facilities offered by DIANA was optimally used. An important aspect of the development process consists of the validation regarding the behavior of the numerical components of the tunnel structure.
