"RIB-IN-ROC" PRE-REINFORCEMENT SYSTEM FOR LARGE UNDERGROUND OPENINGS
This paper summarises the results of a two-and-a-half year research programme, the objective of which was to develop a fundamental understanding of the rib-in-roc method. Through the development of a new model technology, namely three-dimensional physical models which powerfully exploit the results of dimensional analysis, it has been possible to establish the contribution to both permanent and immediate stabilisation of a large underground opening pre-reinforced by the rib-in-roc method. Using the results from these physical models and earlier work by Stillborg and Stephansson and Akesson, this paper demonstrates that the rib-in-roc method is a practical working system of pre-reinforcement.
