摘要

Technical protection against rockfall and other gravitational mass movements is of growing importance, both for the protection of transport routes and settlements as well as for raw-material extraction. Flexible protection systems made of high-tensile steel nets are an economical and powerful mitigation measure, but their design requires a sound experimental basis. This contribution documents the development and operation of a test infrastructure at the Styrian Erzberg, established from 2005 onwards by TRUMER Schutzbauten Ges.m.b.H. together with the Montanuniversität Leoben within a project funded by the Austrian Research Promotion Agency (FFG). It describes the company history and testing philosophy, the suitability of the Erzberg as a large-scale test site, and the three-stage validation approach combining laboratory testing, numerical simulation, and full-scale field tests. By 2021, protection systems up to the high-energy range had been tested under realistic conditions and qualified for use in alpine terrain and in mining. Building on this work, the NAGEMA research centre has been under construction at the same site since the groundbreaking in September 2022; this cable-guided full-scale test infrastructure, developed together with the Montanuniversität Leoben and the University of Natural Resources and Life Sciences Vienna (BOKU), is in its final completion stage in 2026.
