COMPARISON OF TUNNELLING METHODS NATM AND ADECO-RS (2015)

The New Austrian Tunnelling Method (NATM) has been often used in the Czech Republic in last two decades. One of the methods, without application in the Czech Republic, is an Italian method called ADECO-RS, which has reached significant use in Italy and some other countries.
The paper summarizes history of the tunnelling methods and it is closer devoted to NATM and ADECO-RS tunnelling approaches. The basic principles of both methods are set and further the comparison of these methods is made on a theoretical level.
The paper hereinafter includes the analysis of fibreglass face anchors application during the construction of three-aisled Veleslavín Station and the impact assessment of tunnel face anchoring during the excavation of ventilation tunnel on the newly built part of the Prague Metro „V.A“.
The paper also deals with practical knowledge gained during the technical visit of Italian Val di Sambro Tunnel which is built according to ADECO-RS approach. These findings are essential for the correct interpretation of Lunardi method.
