摘要：
The Norwegian University of Science of Technology (NTNU) has a long tradition in preparing empirical prediction models for tunnelling and construction work in rock and soil. Hyundai Engineering and Construction has cooperated with NTNU in gathering TBM production data from recent soft ground tunnelling projects. This research paper aims to present how TBM performance is ranging for various TBM diameters, as well as qualitatively describe how various ground conditions influence the tunnelling performance. The data originates from 9 tunnelling projects, with tunnel diameter from approximately 2 m to more than 12 m. The soil conditions within the collected data range are varying from cohesive soils (clay and silt), to frictions soils mainly consisting of sand and gravel.
