One of the most well known methods using some elements of an observational approach is the New Austrian Tunnelling Method, or NATM. To ensure the safety and stability of the main tunnels, inner supports are used in the main tunnel sections closed to the connection tunnels and emergency protection  WebThe present volume WBI-PRINTNew Austrian Tunneling Method sta-bility analysis and design covers, beside fundamentals of the New Austrian Tunneling Method (NATM), case histories of realized mined tunnels designed and constructed with participation of WBI WebThe New Austrian Tunnelling Method. The method, has often been mentioned as a ‘value engineered’ version of tunnelling due to its use of light, informal support PDF | On Oct, , Karakus M. and others published An insight into the New Austrian Tunnelling Method (NATM) | Find, read and cite all the research you need on ResearchGate NATM is a tunnelling method in which excavation and support proce-dures, as well as measures to improve the ground — which should be distorted as low as possible, — depend on observations of deformation and are continuously adjusted to the encountered conditions.

Consequently, NATM contrasts the design and construct principle, where the The NATM is suitable for the ground with strong stability and low groundwater pressure (maybe with dewatering measure). The New Austrian Tunnelling Method (NATM, in German: NÖT) emerged in the years toand was entitled in this way to be distinguished from the Old Austrian Tunnelling MethodPaulus P. Rahardjo.
