MEASURING FOR FEED-BACK. GEOTECHNICAL MEASUREMENTS FOR THE NEW AUSTRIAN TUNNELLING METHOD

Features which distinguish the New Austrian Tunnelling Method (NATM) are described as - utilisation of rock mass to carry loads, stabilisation of rock mass, continuous measurement of rock mass with design feed-back, and, empirical-scientific design procedures. The article describes typical geotechnical measurements for the NATM. The main load-carrying member is the surrounding rock with stabilising elements such as anchors, Gunite with or without reinforcement, and, arches. Main indicators of the total system are the magnitude and rate of convergence measurements determined at the opened surface and inside the rock mass. The measurements represent the natural response with its known and unknown influences. This has advantages compared with reliance on calculated safety factors and idealised laws of statics.
