<p>For professional tunnel engineers, for whom money and time are in short supply particularly in early stages of a project, this paper critically assesses what works best with the RMR system, today 40 years after its development and extensive accumulated ...

<p>Understanding the interaction between rock bolts and underground rock movement is critical for safe and cost effective underground excavation design. Although early research on this subject involved a balance of theoretical analysis and field measurement, ...

<p>This paper deals with fully grouted rockbolts, both for mining and civil engineering applications. Their mechanical behavior under tensile loads is reviewed theoretically and experimentally. As for the theoretical part, a new solution able to predict the ...

The morphological and geological setting of Greece, the active tectonics and the irrational human activities results to the fact that several natural sightseeing areas or even more, archaeological sitesand monuments are located in areas with unfavourable geotechnical ...

An extensive axial test program has been used to quantify the difference between the static and dynamic capacities (kN/m of embedment) for friction rock stabilisers once sliding starts. Rough simulated boreholes have been developed for the installation and ...

This paper presents the preliminary results of a laboratory testing program aimed at assessing the impact energy dissipation capability of a new rock bolt. The results represent the most up to date findings at this current time. In situ field tests are still ...

This paper presents case studies for both rock mass modulus and rock mass shear strength in an attempt to assess the validity of the approach of using GSI and the Hoek-Brown criterion. It is concluded that for some rock masses the method works well, but in ...

The drive for mechanization of stoping operations on South African platinum, gold and chrome mines is favouring stope support by rock bolts rather than the traditional volumefilling support methods such as mine poles. Many of the stopes are less than two metres ...

A systematic program of testing of different reinforcement systems has been undertaken since 2004. Potentiometers, load cells, accelerometers and high speed video are used to monitor the tests. Software has been developed to analyse the data. The results from ...
